PHP - Image Troubles

Hello Community, good evening!


i am having troubles with starting PHP on linux - [running OpenSuse-Linux]



Could not open input file: -
suse-linux:/usr/perl # php -v
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php5/extensions/readline.so'

well what is wrong here...?

Hi all.

I'm trying to build a dynamic multiple tiered navigation menu that operates on the existence of directories.  So far, I have some code that will read through the document root, and one sub level of directories but I'm not sure how to get into the third level of directories.  Here's what I have so far...

The code:

      $docroot=scandir($_SERVER['DOCUMENT_ROOT']);

      unset($docroot[array_search('.',$docroot)]);

      unset($docroot[array_search('..',$docroot)]);

      unset($docroot[array_search('php',$docroot)]);

      unset($docroot[array_search('css',$docroot)]);

      unset($docroot[array_search('input_forms',$docroot)]);

      $docroot=array_values($docroot);

      

      //Build tier 1

      echo "<div class=\"tier\">";

      echo "<a href=\"/index.php\">Home</a>";

      foreach($docroot as $value1){

         if(is_dir($value1)){

            $t2=scandir($_SERVER['DOCUMENT_ROOT'] . "/" . $value1);

            unset($t2[array_search('.',$t2)]);

            unset($t2[array_search('..',$t2)]);

            $t2=array_values($t2);

            $t1[]=$t2;

            

            echo "<a href=\"/$value1/\">";

            $value1=str_replace("_"," ",$value1);

            $value1=ucwords($value1);

            echo $value1;

            echo "</a>";

         }

      }

      echo "</div>";


The output:
Code: [Select]
[it automatically builds the first tier of the menu with some stylesheet definitions and places it here.  I did this just for testing purposes.]

The script for creating a new file name for the image:

        $validextensions = array("jpeg", "jpg", "png");  //Extensions which are allowed
        $ext = explode('.', basename($_FILES['file']['name'][$i]));//explode file name from dot(.) 
        $file_extension = end($ext); //store extensions in the variable

        $new_image_name = md5(uniqid()) . "." . $ext[count($ext) - 1];
		$target_path = $target_path . $new_image_name;//set the target path with a new name of image

The script creates a new file like:

f6c9b8d9db05366c3504210cded9ddb2.jpg

and moves the file to the "uploads" folder. And then the script also creates a thumbnail with the same file name and moves the file to the "thumbs" folder.   The issue I am having is that the same ID code could happen again for a different image in the database, thus I would be calling a different original sized image than the thumbnail image.   My question is: How to avoid this issue of the same ID code has happened again for a different file. What is the proper way to reference the anchor tag of the thumbnail image to its actual original sized image?   With the script I have the thumbnail image would be coming from the "thumbs" folder and the anchor tag would get referenced to the "uploads" folder to get the original sized image.

Hi, I've read a lot of places that it's not recommended to store binary files in my db.
So instead I'm supposed to upload the image to a directory, and store the link to that directory in database.

First, how would I make a form that uploads the picture to the directory (And what kinda directories are we talking?).

Secondly, how would I retrieve that link? And I guess I should rename the picture..

I'd appreciate any help, or a good tutorial (Haven't found any myself).

How can i edit just one image at on time with a multiple image upload form? I have the images being stored in a folder and the path being stored in MySQL. I also have the files being uploaded with a unique id. My issue is that I want to be able to pass the values of what is already in $name2 $name3 $name4 if I only want to edit $name1. I don't want to have to manually update the 4 images. Here is the PHP:
Code: [Select]
<?php

require_once('storescripts/connect.php');
mysql_select_db($database_phpimage,$phpimage);
$uploadDir = 'upload/';
if(isset($_POST['upload']))
{


foreach ($_FILES as $file)
{

    $fileName = $file['name'];
    $tmpName = $file['tmp_name'];
    $fileSize = $file['size'];
    $fileType = $file['type'];

    if ($fileName != ""){
        $filePath = $uploadDir;
        $fileName = str_replace(" ", "_", $fileName);

        //Split the name into the base name and extension
        $pathInfo = pathinfo($fileName);
        $fileName_base = $pathInfo['fileName'];
        $fileName_ext = $pathInfo['extension'];

        //now we re-assemble the file name, sticking the output of uniqid into it
        //and keep doing this in a loop until we generate a name that 
        //does not already exist (most likely we will get that first try)
        do {
           $fileName = $fileName_base . uniqid() . '.' . $fileName_ext;
        } while (file_exists($filePath.$fileName));

$file_names [] = $fileName;

        $result = move_uploaded_file($tmpName, $filePath.$fileName);
    }


if(!get_magic_quotes_gpc())
{
$fileName = addslashes($fileName);
$filePath = addslashes($filePath);
}
$fileinsert[] = $filePath;
}
}

$mid   = mysql_real_escape_string(trim($_POST['mid']));
$cat   = mysql_real_escape_string(trim($_POST['cat']));
$item  = mysql_real_escape_string(trim($_POST['item']));
$price = mysql_real_escape_string(trim($_POST['price']));
$about = mysql_real_escape_string(trim($_POST['about']));

$fields = array();
$values = array();
$updateVals = array();
for($i = 0; $i < 4; $i++)
{
    $values[$i] = isset($file_names[$i]) ? mysql_real_escape_string($file_names[$i]) : '';

    if($values[$i] != '') {
        $updateVals[] = 'name' . ($i + 1) . " = '{$values[$i]}'"; 
    }
}
$updateNames = '';
if(count($updateVals))
{
    $updateNames = ", " . implode(', ', $updateVals);
}

$update = "INSERT INTO image
               (mid, cid, item, price, about, name1, name2, name3, name4)
           VALUES
               ('$mid', '$cat', '$item', '$price', '$about', '$values[0]', '$values[1]', '$values[2]', '$values[3]')
           ON DUPLICATE KEY UPDATE
                cid = '$cat', item = '$item', price = '$price', about = '$about' $updateNames";
$result = mysql_query($update) or die (mysql_error());

Would like to be able to click on a radio button that represents an image. Once selected and submitted, have that image display on another page. I have an idea, but need some guidance.

BTW, is using php only doable? Is there a simpler or more elegant way to do this?

Thanks all!

Can I get some help or a point in the right direction. I am trying to create a form that allows me to add, edit and delete records from a database. I can add, edit and delete if I dont include the image upload code. If I include the upload code I cant edit records without having to upload the the same image to make the record save to the database. So I can tell I have got the code processing in the wrong way, thing is I cant seem to see or grasp the flow of this, to make the corrections I need it work. Any help would be great!   Here is the form add.php code

<?php require_once ("dbconnection.php"); 
	$id="";
	$venue_name="";
	$address="";
	$city="";
	$post_code="";

Hello,
Five images will be displayed inside a division.
There will be a previous and next button/link.
If someone click the next button the next image will be added in that div and the first image will be gone from that div.
The previous button/link will do the same thing.

Is it possible with php?
I am confused if it's a javascript or ajax question.

Thanks.

Hello,
I've had success creating a cool vanity QR code with rounded edges for my organization by generating a standard QR code, then applying a noise -> median effect in Photoshop to get the edges rounded among some other effects.



Photoshop is great, but I want to automate this. I found a great PHP library to generate QR codes. The part I don't get is the rounding of the hard edges.

I've seen other sites do it like this one.

So far google searches are yielding rounded corner tutorials. Any thoughts on how to do this with GD or ImageMagic?

Best regards,

Chris

Hello

Here is the image-upload.php file code:

   if($extension=="jpg" || $extension=="jpeg") {

   //creates a list of the width and height of the image

   imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,$width,$height);
   
   //set file name
   $filename = $filepath.$newimagename.".".$extension;
   $imagename = $newimagename.".".$extension;
   //uploads new file with name to the chosen directory
   imagejpeg($tmp,$filename,100);

Any help would be appreciated, fairly new to all this!

Thanks!!!

I have a working image upload script that uploads, renames the file and adds filename to the database.

is it possible to include some sort of image resize code? if so can anyone point me in the right direction or better still show some example code and explain how it works etc.

below is my working code:

Code: [Select]
<?php
$rand = mt_rand(1,9999999);
$member_id = $_SESSION['SESS_MEMBER_ID'];
$caption = $_POST["caption"];

    $fileName = basename($_FILES['uploaded']['name']);
$errors = array();
$target = "gallery/";
$fileBaseName = substr($fileName, 0, strripos($fileName, '.'));

   // Get the extension from the filename.
   $ext = substr($fileName, strpos($fileName,'.'), strlen($fileName)-1); 
 
   //$newFileName = md5($fileBaseName) . $ext;
   $newFileName = $target . $rand . "_" . $member_id.$ext;
   
   // Check if filename already exists
   if(file_exists("gallery/" . $newFileName)) 
    {
     $errors[] = "The file you attempted to upload already exists, please try again.";
    }
   // Check if the filetype is allowed.

Many thanks to phpfreaks again.

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

Basically I want to open up a png file with a transparent background which is 48x48 pixels
And set the opacity of this to about 50% of the original.

I have the following to do what I want but just returns an empty image
On imagecolorallocatealpha i have tried setting the alpha value at different values between 0 and 127 with no success as 127 returns a black block


imagecopy($menu,$image,
#Positioning
0,0,
0,0,
#Image size
48,48
);
#Create transparent block
$new_img = imagecreatetruecolor(48, 48);
imagealphablending($new_img, true);
$transparent = imagecolorallocatealpha($new_img, 255, 255, 255, 0);
imagefilledrectangle($new_img, 0, 0, 48, 48, $transparent);
#Put block over original image
imagecopy($menu,$new_img,
#Positioning
0,0,
0,0,
#Image size
48,48
);


The image below shows on top the original and on bottom what I am roughly trying to create



Where am i going wrong?
