Function Help

[jasonhardwick]

ok here is the php i'm having trouble with

 

<?php } 

} else {

//function imageResize(){};

$img_path = "file/".$rows ['file'];

$image_t = getimagesize($img_path); 

$wh = imageResize($image_t[0], $image_t[1], 100);

function imageResize($width, $height, $target) {

if ($width > $height) {
$percentage = ($target / $width);
} else {
$percentage = ($target / $height);
}

$width = round($width * $percentage);
$height = round($height * $percentage);

return "width=\"$width\" height=\"$height\"";
}

echo "<img src=\"$img_path\" $wh />";
}?>

and here is the error

"Fatal error: Call to undefined function: imageresize() in /home/content/j/a/s/jasonhardwick/html/view_topic.php on line 115"

 

line 115 is "$wh = imageResize($image_t[0], $image_t[1], 100);"

the error you're getting is for imageresize, not imageResize. in the code I'm seeing, you did it right.  Why you're getting that error is beyond me. It should be calling imageResize.

It looks to me as though your call is above your function declaration.

 

$wh = imageResize($image_t[0], $image_t[1], 100);

function imageResize($width, $height, $target) {

 

Maybe put the function above the call?

Yeah, if you use PHP 4, you have to declare a function before you can call it (if my memory is right). In PHP 5 you don't need to, though.

Ok I tried to move my function.

<?php } 

} else {

//function imageResize(){};

$img_path = "file/".$rows ['file'];

$image_t = getimagesize($img_path); 

function imageResize($width, $height, $target) {

$wh = imageResize ($image_t[0], $image_t[1], 100);

//function imageResize($width, $height, $target) {

if ($width > $height) {
$percentage = ($target / $width);
} else {
$percentage = ($target / $height);
}

$width = round($width * $percentage);
$height = round($height * $percentage);

return "width=\"$width\" height=\"$height\"";
}

echo "<img src=\"$img_path\" $wh />";
}?>

 

but now my image wont resize  ???

You don't move the function header, you move the WHOLE function.  *Sigh*

 

function imageResize($width, $height, $target) {


if ($width > $height) {
$percentage = ($target / $width);
} else {
$percentage = ($target / $height);
}

$width = round($width * $percentage);
$height = round($height * $percentage);

return "width=\"$width\" height=\"$height\"";
}
$wh = imageResize ($image_t[0], $image_t[1], 100);
