Array Push Error but I've declared Globals

[emilyfrazier]

Hi,

I am getting an error about array push, but I've declared my global variables. The error I get is:

[color=red]warning: array_push() [function.array-push]: First argument should be an array in /home/retnkes9/public_html/drupal/themes/retn/page.tpl.php on line 18.[/color]

Here is my code:
[code]<?php function getRandomImages($count = 1){
global $randomImages;
srand((float) microtime() * 10000000);
$ret = array();
global $ret;
$keys = array_rand($randomImages, $count);
foreach( $keys as $index ){
array_push( $ret, $randomImages[$index] );
}
return  $ret;
}

$randomImages = array();
function addRandomImage( $img = false ) { if( $img ){
global $randomImages;
array_push( $randomImages, $img );
}}
for( $i=1; $i<41; $i++ ){
addRandomImage( "../../../images/random_".sprintf("%02d", $i).".jpg" );
}

?>

<table border="0" cellpadding="0" cellspacing="0" id="header">
  <tr>
   
  <?php
$randomImages = getRandomImages(5);
$first = true;
foreach( $randomImages as $image ){
?>
<?php if( $first ){ $first=false; } else{ ?><td width="16">
<img src="../../../images/randompic_divider.gif" width="16" height="52"></td><?php } ?>
    <td width="52"><img src="<?php echo $image; ?>" width="52" height="52"></td>   
<?php } ?>
    [/code]

I would really appreciate any help on this in advance. It's really messing with me!

Thanks,
Emily

Where do you declare $randomImages?

[emilyfrazier]

Maybe I am not understanding, but I believe I declared $randomImages both in the first and second functions. I declared the array in between the functions. ... I thought making it global would take care of the issue? Thanks for helping,

You can see this error here:

I am really confused on this one, so if you can offer me any futher guidance I would greatly appreciate it!

Thanks,

I think I see the problem.  Remove this line of code:

[code]
global $ret;
[/code]

from the getRandomImages function.

Hmm. Just tried that, but it didn't change anything. Am still getting the same errors.

Here is my code:[code] <?php
function getRandomImages($count = 1){
global $randomImages;
srand((float) microtime() * 10000000);
$ret = array();
$keys = array_rand($randomImages, $count);
foreach( $keys as $index ){
array_push( $ret, $randomImages[$index] );
}
return  $ret;
}

$randomImages = array();

function addRandomImage( $img = false ) { if( $img ){
global $randomImages;
array_push( $randomImages, $img );
}}
for( $i=1; $i<41; $i++ ){
addRandomImage( "../../../images/random_".sprintf("%02d", $i).".jpg" );
}

?>


<table border="0" cellpadding="0" cellspacing="0" id="header">
  <tr>
 
   
  <?php
$randomImages = getRandomImages(5);
$first = true;
foreach( $randomImages as $image ){
?>
<?php if( $first ){ $first=false; } else{ ?><td width="16">
<img src="../../../images/randompic_divider.gif" width="16" height="52"></td><?php } ?>
    <td width="52"><img src="<?php echo $image; ?>" width="52" height="52"></td>   
<?php } ?>[/code]

Thanks for helping!

Sorry, my mac didn't grab all that I thought it did. The code above is now correctly showing what I have.
thanks!
