 |

Hi guys, just wondering if we can use the in_array function in smarty to display arrays. One array will display available categories and the other array will display selected categories. The in_array will display the available categories that have not been assigned.
Thankyou for your help in advance

Perhaps consider building a pre-computed array of unselected items with array_diff?
If you are looking to use in_array in a {if}, then it is easy since PHP functions are allowed as modifiers when security is not enabled (which is the default):
| Code: | | {if $current_item|in_array($selected_array)} |

Hi,
I just came across the exact same problem and found this thread on google, so sorry for a reply three years after the thread was started ^^.
I have the following code inside a for-each loop:
[php]{foreach from=$agegroup item=agegroup name=agegroup}
<td>
<label for="agegroup-{$smarty.foreach.agegroup.iteration}">
<input type="checkbox" name="altersklasse-{$smarty.foreach.agegroup.iteration}" value="{$agegroup.id}" id="agegroup-{$smarty.foreach.agegroup.iteration}" {if $agegroup.id|in_array($agegroupSelected)}checked{/if} /> //This is line 70
{$agegroup.kuerzel}</label>
</td>
{if $smarty.foreach.agegroup.iteration == 6} </tr><tr>{/if}
{/foreach}
[/php]
When I run this code, i get the following error message:
| Quote: | | Parse error: syntax error, unexpected '(' in /<ADRESS-TO-FILE>/templates_c/module^veranstaltungen^veranstaltung^%%7B^7B3^7B308EF8%%hinzufuegen.tpl.php on line 70 |
I am fairly new to smarty, what could be the reason for this error?
If i'm not mistaken, i should be allowed to put bracktes inside the {if}-Statement...or?
Would be awesome if you could help me solve this problem.
Lukas

My bad.
The correct modifier syntax is:
| Code: | | {if $current_item|in_array:$selected_array} |
or just use the php function as usual:
| Code: | | {if in_array($current_item,$selected_array} |
I hate being shown up 3 years after the fact, but that's the beauty of the internet, huh? 
HTH
PS: do read the relevant portions of the manual on modifiers and if statements for the details. In fact, a quick read of the manual will give you lots of good stuff to build from. |
