    1 => Array (3)
      public_group_name => "Disk space"
      attribute_name => "16Go"
      id_product_attribute => "31"

I can display all array thanks to this solution link :

{foreach from=$product.attribute key='id_attribute' item='attribute'} 

<li>

    {foreach from=$attribute key='id_property' item='property'} 
        {$property.public_group_name}
        {$property.attribute_name}
    {/foreach}

</li>

{/foreach}

The result is like this :

• Color Blue Disk space 16Go
• Color Blue Disk space 8Go
• Disk space 16Go Color Yellow
• Disk space 8Go Color Yellow
• Color Metal Disk space 16Go
• Color Metal Disk space 8Go
• Color Black Disk space 8Go
• Color Orange Disk space 16Go
• Color Orange Disk space 8Go
• Color Pink Disk space 16Go
• Color Pink Disk space 8Go
• Color Green Disk space 16Go
• Color Green Disk space 8Go
• Disk space 16Go Color Purple
• Disk space 8Go Color Purple
• Color Black Disk space 16Go

NOw, i want to display result only if a line contain “Blue”.
This array will not been display because he has attribute name = Orange:

33 => Array (2)
        0 => Array (3)
          public_group_name => "Color"
          attribute_name => "Orange"
          id_product_attribute => "33"
        1 => Array (3)
          public_group_name => "Disk space"
          attribute_name => "16Go"
          id_product_attribute => "33"

How can i do that ?
With in_array, can i verify if a value is in a multidimensionnal array ?

Thx

I think this may do the job:

{foreach from=$product.attribute key='id_attribute' item='attribute'} 
{* 
  Test if the first or second element of this array has 
    public_group_name  "Color" 
    attribute_name "Blue"
*}
{if ($attribute[0].public_group_name == "Color" && $attribute[0].attribute_name == "Blue") || ($attribute[1].public_group_name == "Color" && $attribute[1].attribute_name == "Blue")}
<li>

    {foreach from=$attribute key='id_property' item='property'} 
        {$property.public_group_name}
        {$property.attribute_name}
    {/foreach}

</li>
{/if}
{/foreach}
