PHP根据值连续循环遍历数组

Question

I'm having a looping mind-breaking issue which I can't seem to solve myself. Currently working on saving a form input in a webshop. The data:

"personalisation" => array:3 [▼
    0 => "embroidery"
    1 => "printing"
    2 => "embroidery"
  ]
 "repeat" => array:2 [▼
    0 => "true"
    1 => "true"
  ]
"selectedColors" => array:1 [▼
    0 => "3"
  ]

The problem which I have here: I need to loop through the personalisation array to add to my DB. With the embroidery, the repeat value is linked and for the printing the selectedColors is linked. How can I loop through the personlisation array and match the values from the other array?

Answer 1

I really wouldn't recommend designing forms like this, you're basically just sending a jumbled mess to your backend with no association.

You can "correct" the association by filtering the personalisation array and reindexing it so the keys match the other arrays.

$embroderies = array_values(array_filter($array['personalisation'], function($item) {
   return $item === 'embroidery';
}));

foreach($emborderies as $key => $value) {
    // get value from $array['repeat'][$key];   
}

I can't think of any other way than to use a helper array for example.

It could be array('embroidery' => 'repeat', 'printing' => 'selectedColors')

And you start looping through personalization, depending on the value you use it as a key in the helper array, then finally get the wanted value from the array.

1st iteration: 0/embroidery -> embroidery/repeat -> repeat/true

2nd iteration: 1/printing -> printing/selectedColors -> selectedColors/ ...
