problem with image submit button

[sandipan.rcciit]

hi friends,
I already have a code that upload image with re size it.

<form action="<?php echo $_server['php-self'];  ?>" method="post" enctype="multipart/form-data" id="something" class="uniForm">
        <input name="new_image" id="new_image" size="30" type="file" class="fileUpload" />
 <input type="submit" name="submit" value="Submit"><p>
</form>
<?php
        if(isset($_POST['submit'])){
          if (isset ($_FILES['new_image'])){
              $imagename = $_FILES['new_image']['name'];
              $source = $_FILES['new_image']['tmp_name'];
              $target = "images/".$imagename;
              move_uploaded_file($source, $target);
              
              $imagepath = $imagename;
              $save = "images/" . $imagepath; //This is the new file you saving
              $file = "images/" . $imagepath; //This is the original file

              list($width, $height) = getimagesize($file) ; 
                                                         
              $modwidth = 150; 
                                                         
              $diff = $width / $modwidth;
                                                        
              $modheight = $height / $diff; 
              $tn = imagecreatetruecolor($modwidth, $modheight) ; 
              $image = imagecreatefromjpeg($file) ; 
              imagecopyresampled($tn, $image, 0, 0, 0, 0, $modwidth, $modheight, $width, $height) ; 
                                                        
              imagejpeg($tn, $save, 100) ; 
            echo "Large image: <img src='images/".$imagepath."'><br>"; 
        
        
          }
        }
?>

Thats simply because of this line..

if(isset($_POST['submit'])){

when u use an image for input, it doesnt post values as "name"="value" as it does in case of buttons..
instead it will post name_x=... and name_y=... where the values are the x & y coordinates of the point where user clicks the image..
modify ur code to

if(isset($_POST['submit_x'] && isset($_POST['submit_y'])){ // rest remains the same

hope this helps..
cheers!!!

when you using

<input type ="image" src="myfile.jpeg" name="submit" value="Submit">

use

if(isset($_POST['submit_x']) && $_POST['submit_x'] !='' ){

instead of -

if(isset($_POST['submit_x'])){

Hey.

It's a LOT more stable to just do:

<form action="script.php" method="post">
    <input type="hidden" name="isSubmitted" value="1">
    <input type="image" src="myfile.jpeg" name="submit" value="Submit">
</form>

<?php
if(isset($_POST['isSubmitted'])) {
    // etc...
}
?>

You should never actually test to see if the submit button was sent, because there are cases where the button is left out. For instance, if you submit the form by pressing the Enter button, certain browsers do not include the submit button.

It's best to always test a data field, or add a hidden field specifically for that purpose.
