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

we can make :

 

Enter the name of 'thumb_image_name' in a text box:

 

<form name="photo" enctype="multipart/form-data" action="<?php echo $_SERVER["PHP_SELF"];?>" method="post">

Photo <input type="file" name="image" size="30" /> <br /><br />

 

Specify the name of 'thumb_image_name' <input type="text" name="thumb"><br /><br />

 

<input type="submit" name="upload" value="Upload" /><br /><br />

</form>

 

 

 

 

 

After

 

 

$thumb=$_POST['thumb'];

$thumb_image_name = $thumb.".jpg";

Here is my script, just create a folder 'upload_pic' and test

 

 

<?php

//$thumb_image_name = "thumbnail_pic.jpg"; 	// New name of the thumbnail image


$thumb = $_POST["thumb"];

$thumb_image_name=$thumb.".jpg";



$max_file = "1148576"; 						// Approx 1MB
$max_width = "500";							// Max width allowed for the large image
