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

PHP Syntax (Toggle Plain Text)

<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>"; 
 
 
          }
        }
?>

<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>"; } } ?>

Hey.

It's a LOT more stable to just do:

html Syntax (Toggle Plain Text)

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

<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 Syntax (Toggle Plain Text)

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

<?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.
