Searching Within a String to Distinguish Groupings?

[Squire4Hire]

I'm trying to find a practical way to flag Field Definitions to be placed in specific groups on a page based on how their alias is structured.

For example: gp1-city, gp1-style, gp1-location, etc would be parsed into a specific div section where gp2-size, gp2-information would be parsed into another.

Is there a means to search string values to determine whether or not to use the $item in a for loop?

(edit: or even a better way to go about doing something like this...)

Thanks.

If you want a better way you need to give us more details of what you are doing (which module you are using).

For your question you could do something like:

Code: Select all

{if $variablename|substr:0:3 == 'gp1'}...{/if}

A guess at a better solution is to call the custom variables directly instead of using the default {foreach} loop. This will depend on which module is being used.

The general syntax will be something like:

Code: Select all

{$entry->custom_fields->fieldname->value}

You can use this to display the contents of the main var to see where things are in it (replace $entry with the name of the var)

Code: Select all

{$entry|debug_display}

Thanks Jeff, that should get me what I need.

I'm working with LISE objects. I want to be able to choose which definitions are displayed in particular areas of the template. Iterating through the list using this method should allow me to do so.

If you have any suggestions on how to approach it in a more effective way, I'm all ears!

In my opinion iterating through the list is for sample templates (module developer doesn't know which field defs you're going to create).

In your case I'd suggest to create a custom template and use the specific field definitions directly like Jeff suggested.
So, skip the foreach loop for field definitions.

I'm working with LISE Field Definitions. Ideally, I'd like to be able to pre-determine which section on the page the defs would go so I can reduce the amount of screwing around with templates in the event that new field definitions are introduced to the list item.

Using something like this with an if statement that parses the alias should allow me to do so - shouldn't it?

Code: Select all

{foreach from=$item->fielddefs item=fielddef}
		{if $fielddef.alias|substr:0:3 == 'gp1'}...{/if}
{/foreach}
