PHP - Crop Picture Hello Everyone, In Fact, I Have A Script That Makes The Crop Image
Hello everyone,
In fact, I have a script that makes the crop image that works well, I'm stuck on the part of adding a text box to allow to name the image "thumb". I also ask if possible to remove the "PHP_SELF" script and divide it into several pages. Attached script Similar TutorialsI've been creating my own image upload script which takes in several parameters to style an image, however when the function is used new width and new height are specified but I need to use these values to determine cropping coordinates. What I want is when a new width and height is specified, if it is squared i.e. new width is equal to new height AND the original image is not squared i.e. it is a vertical or horizontal rectangle then the central part of that image will be taken. So for example if the user uploads an image 500px high and 100px wide and sets the new width and height both at 100px the new image should be a 100px by 100px square which is taken 200px from the top of the original image. Here is the functions I currently use so far. It's just the coordinates function I can't seem to figure out. Can anyone please help me out:- Code: [Select] //gets the extension of an uploaded file function getExtension($file) { $i = strrpos($file,".");//Gets the position of the "." in the filename if (!$i) { return ""; }//If there is no "." the function ends and returns "" $l = strlen($file) - $i; $ext = substr($file,$i+1,$l); $ext = strtolower($ext); return $ext; } //checks image dimensions and scales both sizes by ratio if it exceeds the max //$w = width, $mw = max width, $h = height, $mh = max height, function checkSize($w, $mw, $h, $mh){ if($w > $mw){//Checks if width is greater than max width $ratio = $mw / $w; $h = $h * $ratio; $h = round($h); $w = $mw; } if($h > $mh){//Checks if height is greater than max height $ratio = $mh / $h; $w = $w * $ratio; $w = round($w); $h = $mh; } return array($w, $h); } //Used to get the coordinates to resize an image by function getCoords(){ } //$f = the file, $ext = file extension, $nw = new width, $nh = new height, $mw = max width, $mh = max height, $nf = new filename, $fo = folder, $des = file size description, $q = quality function imageUpload($f, $ext, $nw, $nh, $mw, $mh, $nf, $fo, $des, $q){ //create image from uploaded file type if($ext=="jpg" || $ext=="jpeg" ){ $src = imagecreatefromjpeg($f); }else if($ext=="png"){ $src = imagecreatefrompng($f); }else{ $src = imagecreatefromgif($f); } //creates a list of the width and height of the image list($w,$h)=getimagesize($f); //sets the coordinates for resizing to 0 by default $dx = $dy = $sx = $sy = 0; //if new width and height are both 0 then a resize is not required so original dimensions need to be validated in case they exceed their max if($nw == 0 && $nh == 0){ if($w > $mw || $h > $mh){//checks if width or height are greater than their max list($w, $h) = checkSize($w, $mw, $h, $mh); } $nw = $w; $nh = $h; }else if($nw == $nh && $w !== $h){//this is for if the resized image needs to be squared but the original image is not a square //COORDS FUNCTION NEEDED HERE } $desext = "";//sets the description extension to "" by default if($des !== 0){//Checks if $des is set or not $desext .= "_".$des;//appends des to $desext ready to be appended to the filename } $foext = "";//sets the folder extension to "" by default if($fo !== 0){//Checks if $fo is set or not $foext .= $fo."/";//appends folder to $foext ready to be appended to the filename } $qv = 100;//sets the quality value to 100 percent by default if($q !== 0){//Checks if $q is set or not $qv .= $q;//sets the quality value to the passed value } $tmp=imagecreatetruecolor($nw,$nh); imagecopyresampled($tmp,$src,$dx,$dy,$sx,$sy,$nw,$nh,$w,$h); $fn = "images/".$foext.$nf.$desext.".jpg";//sets the final filename for upload imagejpeg($tmp,$fn,$qv);//uploads the file //empty variables and clear image imagedestroy($src); imagedestroy($tmp); } i have this awesome script i've used on multiple websites and only now is it giving me trouble. it's always aligned/cropped to the middle of the image but for some reason the smaller thumbnails are cropping to the bottom. Code: [Select] <?php header ("Content-type: image/jpeg"); $file_name=$_GET['f']; $crop_height=$_GET['h']; $crop_width=$_GET['w']; $file_type= explode('.', $file_name); $file_type = $file_type[count($file_type) -1]; $file_type=strtolower($file_type); $original_image_size = getimagesize($file_name); $original_width = $original_image_size[0]; $original_height = $original_image_size[0]; if($file_type=='jpg') { $original_image_gd = imagecreatefromjpeg($file_name); } if($file_type=='gif') { $original_image_gd = imagecreatefromgif($file_name); } if($file_type=='png') { $original_image_gd = imagecreatefrompng($file_name); } $cropped_image_gd = imagecreatetruecolor($crop_width, $crop_height); $wm = $original_width /$crop_width; $hm = $original_height /$crop_height; $h_height = $crop_height/2; $w_height = $crop_width/2; if($original_width > $original_height ) { $adjusted_width =$original_width / $hm; $half_width = $adjusted_width / 2; $int_width = $half_width - $w_height; imagecopyresampled($cropped_image_gd ,$original_image_gd ,-$int_width,0,0,0, $adjusted_width, $crop_height, $original_width , $original_height ); } elseif(($original_width < $original_height ) || ($original_width == $original_height )) { $adjusted_height = $original_height / $wm; $half_height = $adjusted_height / 2; $int_height = $half_height - $h_height; imagecopyresampled($cropped_image_gd , $original_image_gd ,0,-$int_height,0,0, $crop_width, $adjusted_height, $original_width , $original_height ); } else { imagecopyresampled($cropped_image_gd , $original_image_gd ,0,0,0,0, $crop_width, $crop_height, $original_width , $original_height ); } imagejpeg($cropped_image_gd); ?> if i modify the value of original_image_size, it crops to the middle, but if the height is greater than the width it will add black on either side of the image to fill out the designated value. Code: [Select] $original_image_size = getimagesize($file_name); $original_width = $original_image_size[0]; $original_height = $original_image_size[1]; i can't figure out how to get it do both. 0, 0 outputs this: http://www.loudtechinc.com/images/scriptissue/00.png http://www.loudtechinc.com/images/scriptissue/00n2.png 0, 1 outputs this: http://www.loudtechinc.com/images/scriptissue/01.png http://www.loudtechinc.com/images/scriptissue/01n2.png The end goal is to have it fill the desired height and width while cropping to the middle. There is a picture with dimensions of 10000 by 10000 pixels. Need to display a picture with dimensions of 200 by 100. Only need to use native php. I'll explain with an example: I have this image: http://www.fitnessvital.com/images/galeria/caballo-pastando-0.jpg I create a thumbnail of it: http://www.fitnessvital.com/images/galeria/thumbs/caballo-pastando-0.jpg You can see that it's a big image where the important thing is the horse. The grass is not important. So, the best thing to do it's to crop the extra grass and resizing the rest. So the question is: There's a way of recognizing the objects of an image and crop the rest ? Or identify the non important of an imagen and cropt it ? (the same rewrited) Thank you I want to reduce a picture size from 600px * 500px to 60px * 50px size, then crop it become 50px *50px. I have two groups of codes, 1 is to reduce the size of image, other 1 is to crop the image. The problem is they works separately, how to combine this two groups of codes to make them work together? Below is my codes : Code: [Select] <?php //codes of group A - Reduce the size of image from 600px * 500px to 60px * 50px $save2 = "images/users/" . $image_name_2; //This is the new file you saving list($width2, $height2) = getimagesize($file) ; $modwidth2 = 50; $diff2 = $width2 / $modwidth2; $modheight2 = $height2 / $diff2; $tn2 = imagecreatetruecolor($modwidth2, $modheight2) ; $image2 = imagecreatefromjpeg($file) ; imagecopyresampled($tn2, $image2, 0, 0, 0, 0, $modwidth2, $modheight2, $width2, $height2) ; imagejpeg($tn2, $save2, 100) ; //codes of group B - Crop the image from 60px * 50px to 50px * 50px $save3 = "images/users/" . $image_name_3; list($width3, $height3) = getimagesize($file) ; $modwidth3 = 60; $diff3 = $width3 / $modwidth3; $modheight3 = $height3 / $diff3; $left = 0; $top = 0; $cropwidth = 50; //thumb size $cropheight = 50; $tn3 = imagecreatetruecolor($cropwidth, $cropheight) ; $image3 = imagecreatefromjpeg($file) ; imagecopyresampled($tn3, $image3, 0, 0, $left, $top, $cropwidth, $cropheight, $modwidth3, $modheight3) ; imagejpeg($tn3, $save3, 100) ; //save the cropped image ?> As you can see from 2 groups of codes above, 1st group resize the pic then save it to a folder. 2nd group of codes crop the pic then save it into the folder too. My question is ... After 1st group of codes resize the picture, is it necessary to save it into folder before I can crop it? If it is necessary, then I need to write new lines of codes to retrieve the resized pic from the folder for 2nd group of codes to crop it? If it is not necessary, after resizing the pic, how do I pass the pic to 2nd group of codes to crop it? php image-resizing Hi I want to build a script in php that take from user an image and split(crop) the image to 8 or 12 parts equal in the size for puzzel. my problem is how to crope the image to some number 8? I have a link for libery name phpthumb the adress is : http://phpthumb.gxdlabs.com/ In the libery there is a folder examples/crop_basic.php the file crop_basic.php do the missuen but only for one part is crop I dont know how to crop more then one Can you help me please thanks I need to set the width and let height adjust to the proportions of width. Can someone please help me with this? I understand that $canvas_height should be 160, but then the image will crop to whichever side is greatest not by the width only. Code: [Select] <?php $img = "image.jpg"; $canvas_width = 160; $canvas_height = 0; list($img_width, $img_height) = getimagesize($img); $ratio_orig = $img_width / $img_height; if($canvas_width / $canvas_height > $ratio_orig) { $canvas_width = $canvas_height * $ratio_orig; } else { $canvas_height = $canvas_width / $ratio_orig; } $original = imagecreatefromjpeg($img); $canvas = imagecreatetruecolor($canvas_width, $canvas_height); imagecopyresampled($canvas, $original, 0, 0, 0, 0, $canvas_width, $canvas_height, $img_width, $img_height); $dest = "medium/image.jpg"; imagejpeg($canvas, $dest, 100); ?> If is this posible? To have 3-4 pictures on page, user chose one, type in messagge and friends e-mail and send. So friend gets in mail picture and message from user, not just link where he can see picture, but picture insert in mail. How do I do I prevent a broken image icon if there is no image? Here is my code: Code: [Select] <?php if ($_POST){ $county = $_POST['county']; } $con = mysql_connect("localhost","",""); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("", $con); $imageLocation = $row['imageurl1']; $result = mysql_query("SELECT * FROM places WHERE `county` = '".mysql_real_escape_string($county)."' order by `date_created` DESC"); if ( mysql_num_rows($result) > 0 ) { echo "<strong>Click Headers to Sort</strong>"; echo "<table border='0' align='center' bgcolor='#999969' cellpadding='3' bordercolor='#000000' table class='sortable' table id='results'> <tr> <th> Title </th> <th> Borough </th> <th> Town </th> <th> Phone </th> <th> Rooms </th> <th> Bath </th> <th> Fees </th> <th> Rent </th> <th> Image </th> </tr>"; while($row = mysql_fetch_array($result)) { echo "<tr> <td bgcolor='#FFFFFF' style='color: #000' align='center'> <a href='classified/places/index.php?id=".$row['id']."'>" . $row['title'] .

I found this script that uploads a picture onto a folder on the server called images, then inserts the the path of the image on the images folder onto a VACHAR field in a database table. Code: [Select] <?php //This file inserts the main image into the images table. //address error handling ini_set ('display_errors', 1); error_reporting (E_ALL & ~E_NOTICE); //authenticate user //Start session session_start(); //Connect to database require ('config.php'); //Check whether the session variable id is present or not. If not, deny access. if(!isset($_SESSION['id']) || (trim($_SESSION['id']) == '')) { header("location: access_denied.php"); exit(); } else{ // Check to see if the type of file uploaded is a valid image type function is_valid_type($file) { // This is an array that holds all the valid image MIME types $valid_types = array("image/jpg", "image/jpeg", "image/bmp", "image/gif"); if (in_array($file['type'], $valid_types)) return 1; return 0; } // Just a short function that prints out the contents of an array in a manner that's easy to read // I used this function during debugging but it serves no purpose at run time for this example function showContents($array) { echo "<pre>"; print_r($array); echo "</pre>"; } // Set some constants // This variable is the path to the image folder where all the images are going to be stored // Note that there is a trailing forward slash $TARGET_PATH = "images/"; // Get our POSTed variable $image = $_FILES['image']; // Sanitize our input $image['name'] = mysql_real_escape_string($image['name']); // Build our target path full string. This is where the file will be moved to // i.e. images/picture.jpg $TARGET_PATH .= $image['name']; // Make sure all the fields from the form have inputs if ( $image['name'] == "" ) { $_SESSION['error'] = "All fields are required"; header("Location: member.php"); exit; } // Check to make sure that our file is actually an image // You check the file type instead of the extension because the extension can easily be faked if (!is_valid_type($image)) { $_SESSION['error'] = "You must upload a jpeg, gif, or bmp"; header("Location: member.php"); exit; } // Here we check to see if a file with that name already exists // You could get past filename problems by appending a timestamp to the filename and then continuing if (file_exists($TARGET_PATH)) { $_SESSION['error'] = "A file with that name already exists"; header("Location: member.php"); exit; } // Lets attempt to move the file from its temporary directory to its new home if (move_uploaded_file($image['tmp_name'], $TARGET_PATH)) { // NOTE: This is where a lot of people make mistakes. // We are *not* putting the image into the database; we are putting a reference to the file's location on the server $sql = "insert into images (member_id, image_cartegory, image_date, image) values ('{$_SESSION['id']}', 'main', NOW(), '" . $image['name'] .

Check read/write persmissions on the directory"; header("Location: member.php"); exit; } } //End of if session variable id is not present. ?> The script seems to work fine because I managed to upload a picture which was successfully inserted into my images folder and into the database. Now the problem is, I can't figure out exactly how to write the script that displays the image on an html page. I used the following script which didn't work. Code: [Select] //authenticate user //Start session session_start(); //Connect to database require ('config.php'); $sql = mysql_query("SELECT* FROM images WHERE member_id = '".$_SESSION['id']."' AND image_cartegory = 'main' "); $row = mysql_fetch_assoc($sql); $imagebytes = $row['image']; header("Content-type: image/jpeg"); print $imagebytes; Seems to me like I need to alter some variables to match the variables used in the insert script, just can't figure out which. Can anyone help?? I'm using this web script that works successfully. It has a section where I can add a text box to appear upon a web user log-in. Instead, what I'd like to do is make the log-in box (form) disappear as soon as the user logs-in. Can you tell where(how) I can change this code to accomplish that? Thanks for any help.

On my form, I have 50+ variables and not all of them require a response. If inserted, they insert a blank in the DB, instead of NULL. First, does this even matter? If it does, how can I create a function that checks the var to see if its empty, and if empty $var = NULL; Thanks My issue in my php page where i need to show all the news that have the status only active. in my mysql table i have 3 fiels news,posted date and expiry date. on page load i check the status of the news and displays only the active news.For that i am doing the following code,which gives me error. that is on page load, first i select all the news ,update the status inactive for the news which has crossed expiry time i check the status of the news and displays only the active news.For that i am doing the following code,which gives me error. $query1="select time(date_posted),time(expiry_time) from muh_title where status='Active'"; $res=mysql_query($query1); $row=mysql_fetch_row($res); $expiry_time=$row[0];$dateposted=$row[1]; $query11="select addtime(time(date_posted),time(expiry_time)) from muh_title"; $res11=mysql_query($query11); $row11=mysql_fetch_row($res11); $newtime=$row11[0]; $query2="SELECT TIMEDIFF(time(date_posted) ,time(NOW())) FROM muh_title"; $res2=mysql_query($query2); $row2=mysql_fetch_row($res2); $diff=$row2[0]; //while($newtime){ $query5="select *from muh_main_title where date_posted> date_sub(now(),interval (expiry_time) hour-minute )"; //$query3="update muh_title set status='Inactive' "; $res3=mysql_query($query5); } $q="select * from muh_title where status='Active' "; $r= mysql_query($q); $row= mysql_fetch_row($r); echo "<font size='6' color='white'><b><marquee direction='left' loop='-1' align='absmiddle' behaviour='scroll' scrolldelay='90'>$row[1]</marquee></b></font>"; ?> i am sure some where i have lost the flow of code. Hi everyone. I'm completely new to PHP. I've been trying to teach myself to code with it and learn as much as I can for the past few days because it'll definitely come in handy. So far, everything I've learned is just from articles and videos.
Anyway, let's skip the boring stuff.
For literally the whole day today, I've been trying to figure out what the heck is wrong with a script I'm working with. I didn't code it myself. I'm pretty much just modifying it to fit my needs from the generic "template" it comes in.
So here's the issue:
The script is basically used to run a website with user generated content. Users can upload images and write about them. One file of the script deals with the page where the user writes and submits his/her content. Before, I had no issues. I could write a title, a few sentences, upload an image and submit it to the server. Now, seemingly out of nowhere, I'm getting problems everywhere.
Here are the issues:
1. After I fill out the form and hit submit, the page doesn't redirect to my content.
2. As soon as I hit the submit button, the page goes blank (white screen) and gets stuck on mydomain.com/submit (which is the same page where I filled out the form)
3. Along with the white screen, I'm getting the following error on top of it:
Notice: Undefined index: name in .../public_html/include/p-page-ask.php on line 126
I've spent the last 12 hours trying to fix this. For issue 3, I've read that you can use the "isset" function to fix it. But I have no idea how to code that into it. I tried different variations, but none worked to make it go away. For issue 2, I'm guessing this is a fatal php error? I have no idea what's causing it. If I view source, I just get a blank page. For issue 1, I'm guessing this has to do with issue 2 halting the page from redirecting? I'm pretty sure 2 and 3 are different errors because I've read that even if 3 occurs, the page still loads.
I've turned on all the error reporting and display functions in my php.ini file. I made sure that the server is using that particular file with phpinfo(). (Although I didn't restart my server. I have no idea how to. I'm on a shared environment). After making these changes, I still don't see any additional errors, just the notice on a blank page.
I've looked through the code for syntax errors, but couldn't find any.
I've even installed xampp and made a test environment. I read through the documentation and watched tutorials on YouTube to set it up. (I've had absolutely 0 experience with this kind of stuff). I downloaded all the exact files from my online server into my localhost environment. Funny enough, it works just fine on my machine. It doesn't even throw errors locally. However, it doesn't work online. What the heck is going on?
The only differences I can think of between the two environments are the php versions and sql database versions (xampp is newer)...but I don't know if that really makes a difference because the script USED to work on my server, so it must be compatible with the set versions.
I've been editing the files in the script for quite a while now. I know when I first started, the uploads would work just fine. Then I didn't upload for a while because I already tested it out and knew it worked, so I just continued working on the script. I may have modified something that's now causing the errors. But then wouldn't that cause the localhost environment to fail too? If the files are exactly the same, how could one fail to work? That makes no sense at all. I'm looking at this code lost and hopeless. I'm getting sad.
If ANYONE has any suggestions on fixing this, PLEASE let me know. I don't know what to do anymore.
If you need me to upload any of the other files, just ask.

Hi Guys, I am trying to disguise my php script as a .gif file for the purposes of a shopping cart. Basically, you click on the .gif which is placed on the page and it takes you to an image unless it has variables attached to it. Google use this for their checkout so I know this is possible. Does anyone have any ideas how I would go about doing this? Thanks in advance, Jacob. I have 23 products in a db, all with a unique ID that Im creating a user site for. Some of the items have 1 or 2 images and others have as many as 30 images. In my db I have a field called "pics". All the images are saved as a .jpg, according to their id on the server. So if item 1 has 10 images the files a "1_001.jpg," "1_002.jpg," ect. How do I create a script that will display the correct amount of images based on the number in the db. I was going to do something like this: Code: [Select] if ($row['pics'] =="1") { $pictures = '<img src="pictures/'.$id.'_001.jpg" width="200" alt="" />'; } elseif ($row['pics'] =="2") { $pictures = '<img src="pictures/'.$id.'_001.jpg" width="200" alt="" /><img src="pictures/'.$id.'_002.jpg" width="200" alt="" />'; } elseif ($row['pics'] =="3") { $pictures = '<img src="pictures/'.$id.'_001.jpg" width="200" alt="" /><img src="pictures/'.$id.'_002.jpg" width="200" alt="" /><img src="pictures/'.$id.'_003.jpg" width="200" alt="" />'; } but that would just be retarded... Thank you! hello i have this php code to show the last image upload in a folder and the result is this http://theplattan.com/screenlive2/Screenshooter2.php this code must be in the same image folder to work. I need add a php code from my joomla website but i dont know where i can change the path image folder on this script. i have tried by my self to change rad 33 $files = dirList('.'); to $files = dirList('screenlive2'); but this show only the list and not the image, somebody have any idea? Code: [Select] 1: <html> 2: <head> 3: <style type="text/css"> 4: #files { float: left; font-size: small; } 5: #image { float: right; } 6: .links { float: right; left: -40px; position: relative; } 7: .selected { font-weight: bold; } 8: </style> 9: </head> 10: <body> 11: 12: <?php 13: 14: function dirList ($directory) 15: { 16: $results = array(); 17: $handler = opendir($directory); 18: while ($file = readdir($handler)) { 19: if ($file != '.' && $file != '..') 20: { 21: $suffix = "gif"; 22: 23: if( substr($file, -3) == $suffix ) 24: { 25: $results[] = $file; 26: } 27: } 28: } 29: closedir($handler); 30: return $results; 31: } 32: 33: $files = dirList('.'); 34: 35: arsort($files); 36: 37: //$files = array_reverse( $files ); 38: 39: echo "<div id='files'><ul>"; 40: 41: $prev = ""; 42: $next = ""; 43: $last = ""; 44: 45: foreach( $files as $entry ) 46: { 47: if( isset($_GET['sel']) == false ) 48: { 49: $_GET['sel'] = $entry; 50: } 51: 52: $style = ""; 53: 54: if( $_GET['sel'] == $entry ) 55: { 56: $style="selected"; 57: $selected = $entry; 58: $prev = $last; 59: } 60: 61: echo "<li class='".$style."'><a href='i.php?sel=".$entry."'>"; 62: print_r( $entry ); 63: echo "</a></li>"; 64: 65: if( ($last == $selected) && ($last != "") ) 66: { 67: $next = $entry; 68: } 69: 70: $last = $entry; 71: } 72: 73: echo "</ul></div>"; 74: 75: echo "<div id='image'><img src='".$selected."' alt=''/></div>"; 76: 77: echo "<p class='links'>"; 78: 79: if( $prev != "" ) echo "<a href='i.php?sel=".$prev."'>Up</a>"; 80: echo "<br/>"; 81: if( $next != "" ) echo "<a href='i.php?sel=".$next."'>Down</a>"; 82: 83: echo "</p>"; 84: 85: ?> 86: 87: </body> 88: </html> |
