JavaScript - Cropping Photos With Javascript And Php
All,
I'm trying to have a user upload a photo and then crop the image if they so desire. I want them to be able to select the selected area and then basically use PHP to create the new image. I found a script like this: http://www.dhtmlgoodies.com/index.ht...ipt=image-crop I was just wondering if anyone has any other recommendations or a better way to go about doing this? Thanks in advance for any help. Similar TutorialsI need to do image cropping through javascript(without jquery) my requirement is just to get the coordinates through some callback function whenever user crop the image and click an ok button please help me with some javascript code here Hi all, I'm looking for an image cropping tool script that I can provide on my website for users to crop their uploaded photo on my site and I can store them directly on my host. (instead of having to go to another page, or open up photoshop etc, crop their photo, save, and then upload to my site) I see some websites providing this service, does anyone know any scripts that allows me to do this? Thanks in advance! Hello, I need to know that is there any script available which allows me to upload an image and after uploading it will allow me to crop an image like we do in photoshop via pen tool. In photoshop when we use pen tool, it apply nodes against the images and user can easily change nodes via mouse to change the position of cropping. Is there any type of script available which provides this functionality? Thanks Hey guys, I'm working on a user website and have got the upload form working and the cropping working, also got the image in my profile, all works great. A few things I need tho and wondering if you could help. I need to stop the form from resubmitting the image when I refresh the upload.php page below upload.php PHP Code: <?php define('INCLUDE_CHECK',true); require 'connect.php'; session_start(); $session_id ='1'; $username = $_SESSION['user']; $upload = $_POST['upload']; $new_name = "small".$username.".jpg"; $path = "uploads/"; ?> <html> <head> <title>My Network</title> </head> <link rel="stylesheet" type="text/css" href="css/imgareaselect-default.css" /> <script type="text/javascript" src="js/jquery.min.js"></script> <script type="text/javascript" src="js/jquery.imgareaselect.pack.js"></script> <script type="text/javascript"> function getSizes(im,obj) { var x_axis = obj.x1; var x2_axis = obj.x2; var y_axis = obj.y1; var y2_axis = obj.y2; var thumb_width = obj.width; var thumb_height = obj.height; if(thumb_width > 0) { if(confirm("Do you want to save image..!")) { $.ajax({ type:"GET", url:"ajax_image.php?t=ajax&img="+$("#image_name").val()+"&w="+thumb_width+"&h="+thumb_height+"&x1="+x_axis+"&y1="+y_axis, cache:false, success:function(rsponse) { $("#cropimage").hide(); $("#thumbs").html(""); $("#thumbs").html("<img src='uploads/"+rsponse+"' />"); } }); } } else alert("Please select portion..!"); } $(document).ready(function () { $('img#photo').imgAreaSelect({ aspectRatio: '1:1', onSelectEnd: getSizes }); }); </script> <?php $valid_formats = array("jpg", "png", "gif", "bmp"); if(isset($_POST['submit'])) { $name = $_FILES['photoimg']['name']; $size = $_FILES['photoimg']['size']; if(strlen($name)) { list($txt, $ext) = explode(".", $name); if(in_array($ext,$valid_formats) && $size<(1024*1024)) { $actual_image_name = time().substr($txt, 5).".".$ext; $tmp = $_FILES['photoimg']['tmp_name']; if(move_uploaded_file($tmp, $path.$actual_image_name)) { mysql_query("UPDATE user SET profile_image='$actual_image_name' WHERE id='$username'"); $image="<h1>Please drag on the image</h1><img src='uploads/".$actual_image_name."' id=\"photo\" style='max-width:500px' >"; $profile_image="<img src='uploads/".$new_name."' style='max-width:500px' >"; } else echo "failed"; } else echo "Invalid file formats..!"; } else echo "Please select image..!"; } ?> <body> <div style="margin:0 auto; width:600px"> <?php echo $image; ?> <div style="padding:5px; width:600px"> <?php echo $profile_image; ?> </div> <div style="width:600px"> <form id="cropimage" method="post" enctype="multipart/form-data"> Upload your image <input type="file" name="photoimg" id="photoimg" /> <input type="hidden" name="image_name" id="image_name" value="<?php echo($actual_image_name)?>" /> <input type="submit" name="submit" value="Submit" /> </form> </div> </div> </body> </html> ajax_image.php PHP Code: <?php define('INCLUDE_CHECK',true); require 'connect.php'; session_start(); $username = $_SESSION['user']; $upload = $_POST['upload']; $t_width = 100; // Maximum thumbnail width $t_height = 100; // Maximum thumbnail height $new_name = "small".$username.".jpg"; // Thumbnail image name $path = "uploads/"; if(isset($_GET['t']) and $_GET['t'] == "ajax") { extract($_GET); $ratio = ($t_width/$w); $nw = ceil($w * $ratio); $nh = ceil($h * $ratio); $nimg = imagecreatetruecolor($nw,$nh); $im_src = imagecreatefromjpeg($path.$img); imagecopyresampled($nimg,$im_src,0,0,$x1,$y1,$nw,$nh,$w,$h); imagejpeg($nimg,$path.$new_name,90); mysql_query("UPDATE user SET profile_image_small='$new_name' WHERE username='$username'"); echo $new_name."?".time(); exit; } ?> And I also need a live preview of cropping. So when the user is selecting what area of the Large image they want as there final thumb image, they can see the thumb change to that selection at the same time. The thumb is below the uploaded image, and without refreshing, which I cannot yet do because of the form resubmit, you can't see the final image until you go back to your profile. If I didn't make the above clear enough, please tell me. Thanks for any help and suggestions. Hello I Don't have any experience with JavaScript, I found this on internet for photo slideshow.

I would like to have a code on my page that causes two or more photos to change between each other. For example, photo 1 is shown for a little while, then it switches to photo 2, etc. I would also like to switch text that goes along with the photos. I would like my layout to look like this: Photo / Text about Photo and have both switch after a little while, to the next photo and text. Hope this makes sense. Thanks in advance! Hi All! I'm somewhat new to CSS/Javascript but need assistance finding code that will help me accomplish the tool on the following page: http://www.constantcontact.com/index.jsp If you look at the rotating information on the left-side of the Constant Contact website, I would like to be able to have that same functionality on my website. If anyone knows how this is accomplished, any assistance would be greatly appreciated. I am looking for the following functionality: 1) Have the ability to hover over each number to change the main photo 2) Have the script advance the main photo on its own 3) Be able to click the main photo when it is selected Any questions, let me know! Thanks, Eric I'm using the classic theme for galleria to create a basic image gallery. http://galleria.io/themes/classic/ The gallery is for a photo retoucher who has some before/after photos that I want to switch in and out with a mouseover. Basically when the user hovers over the main image an unedited version of the image will show, when they mouse out the image will revert back to the original. I'm not sure how to achieve this with galleria. I thought I could target the img tags but that doesn't seem to be working. I'm relevantly inexperienced with javascript so I'm not sure how to target the imgs through galleria or if this can be accomplished in an effective way. (maybe changing the src?) I'm not sure if there is anyone familiar enough with galleria to help me out, but i figured asking can't hurt. Any sort assistance would be greatly appreciated. Hello everyone, I was wanting to know how you add links to Adobe Lightroom gallery photos? Here is the xml gallery code I am trying to add links to: <?xml version="1.0" encoding="UTF-8"?> <simpleviewerGallery maxImageWidth="1024" maxImageHeight="1024" textColor="0xFFFFFF" frameColor="0xFFFFFF" frameWidth="1" stagePadding="40" thumbnailColumns="2" thumbnailRows="3" navPosition="left" title="" enableRightClickOpen="true" backgroundImagePath="" imagePath="images/" thumbPath="thumb/"> <image> <filename>1.jpg</filename> <caption></caption> </image> <image> <filename>2.jpg</filename> <caption></caption> </image> <image> <filename>3.jpg</filename> <caption></caption> </image> <image> <filename>4.jpg</filename> <caption></caption> </image> <image> <filename>5.jpg</filename> <caption></caption> </image> <image> <filename>6.jpg</filename> <caption></caption> </image> <image> <filename>7.jpg</filename> <caption></caption> </image> <image> <filename>8.jpg</filename> <caption></caption> </image> <image> <filename>9.jpg</filename> <caption></caption> </image> </simpleviewerGallery> I have Adobe Lightroom 3. So far browsing through various tutorials and help notes I have not found a way to do this. However, I am hoping there is in fact a way to do this.

I am trying to find a script that allows you to open multiple browser tabs and then close each of those tabs, either one by one or all at once. Does anyone know how to do this please? Thanks so much for your help. I want to have another go at Javascript. I have several books on the subject but I find that my eyesight is a major problem. Therefore I want to try an on-line solution, preferably free. I have Googled, but there are so many that I am almost dizzy with the choices. Perhaps someone could recommend one. Not too fussy visually. My knowledge is VERY basic. Frank Does anyone know how to make URL links that use Javascript still work when users have Javascript disabled on their browser? The only reason I'm using JS on a URL is because my link opens a PDF file, and I'm forcing it not to cache so users have the latest version. I tried the <script><noscript> tags, but I'm not sure if I'm using it correctly, as my URL completely disappears. Below is my HTML/Javascript code: <p class="download"> <script type="text/javascript">document.write("<span style=\"text-decoration: underline;\"><a href=\"javascript:void(0);\" onclick=\"window.open( 'http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf?nocache='+ Math.floor( Math.random()*11 ) );\" >The Child Magazines Media Kit</a></span> (PDF 1 MB) ");</script> <noscript><span style="text-decoration: underline;"><a href="http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf" >The Child Magazines Media Kit</a></span> (PDF 1 MB)</noscript> </p> Thanks for any help, Michael Hi, I have the following code snippet: test.html ====== <script language="javascript" type="text/javascript"> var testVariable = "test"; </script> <script language="javascript" type="text/javascript" src="test.js"> </script> test.js ===== var testVariable = window.top.testVariable; In firefox, I'm able to access testvariable defined within test.html in test.js.

Hi Guys, I am new at JavaScript and start to do some tutorials.What I am trying to do here is prompting user to input a name and if the name was valid the page(document) will display with all objects like the button.But if user enter a wrong name then the button will be disabled! I create the following code but it did not work <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>New Web Project</title> <script language="JavaScript" type=""> function changeColor(){ document.bgColor = "Gray"; } </script> </head> <body> <script language="JavaScript" type="text/javascript"> var person = ""; person = prompt('What is Your Name:'); if (person == "Foo") { document.write("<h1 />Welcome " + person); document.bgColor = "Yellow"; } else { document.write("<h1 />Access Denied!!!!"); document.bgColor = "Red"; document.getElementById("gree").disabled = true; } </script> <div> <p/><input id="gree" type="button" value="Gray " onClick="changeColor();"> </div> </body> </html> as you can see I used the: document.getElementById("gree").disabled = true; but it did not work , could you please give an idea how I can solve this problem? Thanks I want to insert this js snippet Code: function addText(smiley) {
document.getElementById('message').value += " " + smiley + " ";
document.getElementById('message').focus();
return false;
}
to a loaded iframe with name&id chtifrm. I can access it & change embed something in its html via using something like: Code: $(parent.chtifrm.document.body).append('<div id=\"smly\" style=\"cursor:pointer;float:left;top:200px;display:none;position:absolute;\"><\/div>');
.... Code: parent.chtifrm.document.getElementById('chatbox_option_disco').style.display == 'none'
but how do I insert js in the head of loaded iframe? I got an index.php Code:
<html>
<form action="bacakomik.php" method='post'>
<select name="kodekomik">
<option value='../komik1/|23'>Judul Komik1</option>
<option value="../komik2/|20">Judul Komik2</option>
<option value="../komik3/|10">Juduk Komik3</option>
<option value="../komik4/|20">Judul Komik4</option>
</select>
<input type="submit" />
</form>
<?php
echo ('<select>');
echo ('<option value= "'.$i.'">'.'Page '.$i.'</option>');
echo ('</select>');
?>
</html>
As you can see, each of the option brings specific value "../komik1/|23" komik1 is a directory | is a delimiter 23 is the pages in one chapter and can be considered also as how many images are there on a specific directory This is my bacakomik.php Code: <?php
$dirkomik = $_POST['kodekomik'];
$exploded = explode("|", $dirkomik);
echo ($exploded[0]); //picture directory
echo ("<br>");
echo ($exploded[1]); //total page in the comic
$pagecount = (int)$exploded[1];
//Take last posted value, process it right away
echo ('<FORM name="guideform"> ');
echo ('<select name="guidelinks">');
$i=1;
do {
echo ('<option value= "'.$i.'">'.'Page '.$i.'</option>');
$i= $i+1;
}while($i <= $pagecount); //Printing option and select
echo ("</select>");
?>
<input type="button" name="go" value="Go!" onClick="document.getElementById('im').src=document.guideform.guidelinks.options[document.guideform.guidelinks.selectedIndex].value+'.png';"> </FORM>
<img src="img0.jpg" id="im">
With the current code on bacakomik.php, I only can change the img src of id "im" in the same directory only. What I want is that the Javascript could "add" the "$exploded[0]" variable so that the picture can be loaded from different directory. Anyone can do this? I believe that the fix should be somewhere on input tag inside OnClick, or do you know where? Anyway, I found this on the net http://p2p.wrox.com/php-faqs/11606-q...avascript.html Please help me to those who can... Hey, I've got to make the values of some textboxes change the co-ordinates of my sprite on a canvas and havent a clue on how to do it, Here is my form with the two textboxes and submit button: <form> x: <input type="text" name="x" /><br /> y: <input type="text" name:"y" /><br /> <input type="submit" value="Submit"/><br /> </form> And i need it so that they change the values of these: //this shows where my sprite will start on the canvas var block_x; var block_y; searched the internet for hours and cant really find anything i understand or works. any help is much appreciated Hi Guys I am trying to modify the functionality of my page. I want to be able to activate this piece of code using another javascript function. This is the code I want to activate: Code: <script type="text/javascript"><!--
$('#button-cart').bind('click', function() {
$.ajax({
url: 'index.php?route=checkout/cart/update',
type: 'post',
data: $('.product-info input[type=\'text\'], .product-info input[type=\'hidden\'], .product-info input[type=\'radio\']:checked, .product-info input[type=\'checkbox\']:checked, .product-info select, .product-info textarea, .date_data input[type=\'text\']'),
dataType: 'json',
success: function(json) {
$('.success, .warning, .attention, information, .error').remove();
if (json['error']) {
if (json['error']['warning']) {
$('#notification').html('<div class="warning" style="display: none;">' + json['error']['warning'] + '<img src="catalog/view/theme/default/image/close.png" alt="" class="close" /></div>');
$('.warning').fadeIn('slow');
}
for (i in json['error']) {
$('#option-' + i).after('<span class="error">' + json['error'][i] + '</span>');

}

$('#notification').html('<div class="success" style="display: none;">' + json['success'] + '<img src="catalog/view/theme/default/image/close.png" alt="" class="close" /></div>');
$('.success').fadeIn('slow');
$('#cart_total').html(json['total']);
$('html, body').animate({ scrollTop: 0 }, 'slow');
}
}
});
});
//--></script>
And this is how I want the format of the function to be: function testsession() { if there is a session called 'hiredate' { activate the script above } else { var el = document.getElementById("product_data"); } } I just dont know how to write this in javascript Could you help me if possible please All -- I have a JavaScript config file called gameSetting.js which contains a bunch of variables which configures a particular game. I also have a shared JavaScript library which uses the variables in gameSetting.js, which I include like so: <script type="text/javascript" src="gameSetting.js" ></script> <script type="text/javascript" src="gameLibrary.js" ></script> In gameSetting.js I have: $(document).ready(function() { // call some functions / classes in gameLibrary.js } in Firefox, Safari, and Chrome, this works fine. However, in IE, when it's parsing gameSetting.js, it complains that the functions that live in gameLibrary.js aren't defined. When it gets to parsing gameLibrary.js, the variables in gameSetting.js are reported as not being defined. I've tried dynamically bootstrapping the gameLibrary file using this function in document.ready for dynamic load... $.getScript("gameLibrary.js"); However, the same problem still happens in IE, where when it parses the files individually it's not taking into context the file/variables that came before, so it's not an out of load order problem. My options a 1) collapsing all the functions in gameLibrary.js and variables in gameSetting.js into one file. However, this is not practical because this is dealing with literally hundreds of games, and having a gameLibrary.js in ONE location for ONE update is what makes most logical sense. 2) figure out a way to get this to work where variables in file1 are accessible to file2 in IE (as it seems they are in other browsers). jQuery seems to be able to have multiple plugins that all refer to the based jQuery-1.3.2.js, so I know there is a way to get this to work. Help appreciated. Nero I wrote a log function that took note of various function calls. Thinking that functions are first class objects, and objects have properties, I made the name of each logged function a property of that function, e.g., brightenInnerPara.name = "brightenInnerPara"; Every browser I tried (Firefox, MSIE, Opera, Chrome, Safari) accepted the assignment, no problem. In Firefox and MSIE, the result was what I wanted: brightenInnerPara.name == "brightenInnerPara" But in the others, the result was: brightenInnerPara.name == null Question 1. Which Javascript is correct here? I favor Firefox and MSIE, not merely because they were willing to give me what I wanted, but also because it makes no sense to accept an assignment statement without throwing an error and then give it a null semantics, like Chrome, Opera, and Safari did. I found a workaround, using assignments like this: brightenInnerPara.prototype.name = "brightenInnerPara"; To my surprise, that worked in every browser. But I don't know why. It seems that such assignments are enough to cause each function to have its own distinct prototype. Question 2. Just how inefficient is my workaround, and why does it work? |
