Smarty functions

[seymourjames]

I have a wish to set the alt tag on images in viewlistings according to a simple function which I would like to return an array.

Here is a function which I want to return an array phrases which have been mixed up.

<?php
function smarty_function_randphrase($params, &$smarty)
{
$phrase = array("Property In France", "French Property", "French Property For Sale", "Property In France For Sale", "Property For Sale In France ", "Property In France", "French Properties", "French Properties For Sale", "Properties In France For Sale", "Properties For Sale In France ");

shuffle($phrase);

return $phrase; is this correct?
}
?>

In viewlisting, I would like to add an alt tag from the output of the array.


{html_table_adv loop=$data cols=$cols table_attr='width="100%"'}
<div class="photo_view">
<div class="feat_img"><img src="photos/[[image]]" width="254" height="218" class="image" border="0" alt="[[randphrase]]" /></div>
<div class="photo_text">[[title]]</div></div>
{/html_table_adv}

I just cannot get the syntax. Any help would be greatly appreciated.

Try this:

PHP Code:


<?php
function smarty_function_randphrase($params, &$smarty)
{
$phrase = array("Property In France", "French Property", "French Property For Sale", "Property In France For Sale", "Property For Sale In France ", "Property In France", "French Properties", "French Properties For Sale", "Properties In France For Sale", "Properties For Sale In France ");

return shuffle($phrase);
}
?>

Then: alt="{randphrase}"

Better but I get a bunch of alt = "1" in the tags. I do not get the array strings. Any more ideas. Bring back 'C' is what I say. i think it is something in the alt="{randphrase}" which is not gelling. I want to eventually use this to generate tags when people do not enter descriptions on their photos. Bare or empty alt tags is not so good.

How about this:

PHP Code:

 
<?php
function smarty_function_randphrase($params, &$smarty)
{
$phrase = array("Property In France", "French Property", "French Property For Sale", "Property In France For Sale", "Property For Sale In France ", "Property In France", "French Properties", "French Properties For Sale", "Properties In France For Sale", "Properties For Sale In France ");

$rand_keys = array_rand($phrase, 2);
return $phrase[$rand_keys[0]];
}
?>

Very nearly. alt ="Property In France" each time it goes through the loop. Just a case now of getting it to move along the array the same number of times as there are images to be displayed.

Ok how about this:

PHP Code:

  
<?php
function smarty_function_randphrase($params, &$smarty)
{
$phrase = array("Property In France", "French Property", "French Property For Sale", "Property In France For Sale", "Property For Sale In France ", "Property In France", "French Properties", "French Properties For Sale", "Properties In France For Sale", "Properties For Sale In France ");
$i = rand(0, 8);
return $phrase[$i];
}
?>

The $i=rand(0,8); 8 is the number of array elements.
