Passing an Variable from one PHP File to another

[stublackett]

Hi Guys,

 

I'm working on an image resizer, to create thumbnails for my page. The resizer works on principle of include a DIRECT link to the image. But what I want to do is put in the PHP Variable in the URL string, so that it points to that file and resizes it accordingly.

 

My code is as follows :

<img src="thumbnail.php?image=<?php echo $row_select_property['image_url']; ?>

 

Image Resize :

<?php 
// Resize Image To A Thumbnail

// The file you are resizing 

$image = '$_GET[image_url]'; 

//This will set our output to 45% of the original size 
$size = 0.45; 

// This sets it to a .jpg, but you can change this to png or gif 
header('Content-type: image/jpeg'); 

// Setting the resize parameters
list($width, $height) = getimagesize($image); 
$modwidth = $width * $size; 
$modheight = $height * $size; 

// Creating the Canvas 
$tn= imagecreatetruecolor($modwidth, $modheight); 
$source = imagecreatefromjpeg($image); 

// Resizing our image to fit the canvas 
imagecopyresized($tn, $source, 0, 0, 0, 0, $modwidth, $modheight, $width, $height); 

// Outputs a jpg image, you could change this to gif or png if needed 
imagejpeg($tn); 
?>

 

What I am trying to do is pass on the variable "image=<?php echo $row_select_property['image_url']; ?>" to the Thumbnail script. At the moment I am passing it through the URL string, but it doesnt  seem to load the graphic.

 

I'll try expand on this more, should you have questions as I am finding it a little difficult to explain.

 

Thanks in advance.

have you tested the value of $row_select_property['image_url']?

[stublackett]

Yeah, It's

propertyimages/picture1.jpg

[litebearer]

perhaps this?

<a href="thumbnail.php?image=<?php echo $row_select_property['image_url']; ?>"><img src="<?php echo $row_select_property['image_url']; ?>" alt=""></a>

You are using $image = '$_GET[image_url]'; I'm pretty sure that won't retrieve the GET value from the URL.

 

Try using $image = $_GET['image_url'];, try this and see if it is the issue.

Tried that Cheers Paul, Wasnt correct but put me on the right root.

 

I needed...

$image = $_GET['image'];
