Add a new field to array elements in a foreach PHP - Laravel

Question

I have this variable:

$families = array(
    array(
        'expand'      => '',
        'family_id'   => 'AAER',
        'active'      => true,
        'description' => 'Wall Art',
        'group_id'    => 5
    ),
    array(
        'expand'      => '',
        'family_id'   => 'EERR',
        'active'      => true,
        'description' => 'Personalised Mugs',
        'group_id'    => 4
    ),
);

And I want add to my $families items a field called 'href', like this:

$families = array(
    array(
        'href'        => 'http://mipage/wall-art/AAER',
        'expand'      => '',
        'family_id'   => 'AAER',
        'active'      => true,
        'description' => 'Wall Art',
        'group_id'    => 5
    ),
    array(
        'href'        => 'http://mipage/personalised-mug/EEER',
        'expand'      => '',
        'family_id'   => 'EERR',
        'active'      => true,
        'description' => 'Personalised Mugs',
        'group_id'    => 4
    ),
);

To do this I iterate $families in a foreach loop:

foreach($cat['families'] as $cat_fam) {
    $cat['families'][]['href']  = 'http//mysite/'.str_slug($cat_fam).'/'.$cat_fam['family_id'];
}

But this not works for me.

How can I make this?

You need to specify how it is not working...

You've to repalce empty [] with the specific key. For this update foreach block to get key of the element and use that inside foreach loop.

$cat['families'][$key] which points to individual element of the families array.

Like this,

foreach($cat['families'] as $key=>$cat_fam) {
    $cat['families'][$key]['href']  = 'http//mysite/'.str_slug($cat_fam).'/'.$cat_fam['family_id'];
}

just iterate over the array, and add a key ahref

 $newArray= array();
 foreach($families as $innerArray){
   $innerArray['ahref']='YOUR LINK HERE'; 
   $newArray[] = $innerArray;
 }

$families = $newArray ;//if you want to update families array

It should be $newArray[] = $innerArray; instead.

@AlokPatel yes, typo, actually I quickly tested the output on my machine and updated it here..

Do something like:

$href = array('href'=>'http://mipage/wall-art/AAER');
$combined_array = array_combine($families[0],$href);

Don't tested but you can try or modify as per your use

Please try this:

I think you also forgot to add index description in your str_slug call.

foreach($cat['families'] as &$cat_fam) {
    $cat_fam['href'] = 'http://mysite/'.str_slug($cat_fam['description']).'/'.$cat_fam['family_id'];
}

You can use the php function array_walk

Liek this :

array_walk($cat['families'], function(&$family){
   $family['href'] = 'http//mysite/'.str_slug($family).'/'.$family['family_id'];
 });

note the $family variable is passed by reference.
