How to Handle HTML Form Input as an Array of Levels with

HTML Form Input as an Array

The provided form intends to capture an array of levels, each level consisting of a title and a build time. The desired output is an array with each level represented by its title and build time, as shown in the example provided.

Suggested Solution:

To achieve the desired output, modify the input names slightly:

<input type="text" class="form-control" placeholder="Titel" name="levels[level][]">
<input type="text" class="form-control" placeholder="Titel" name="levels[build_time][]">

Adding the square brackets at the end of the names tells PHP that the input should be treated as an array. Subsequently, upon form submission, PHP will automatically populate an array named "levels" with subarrays for "level" and "build_time."

Using Dynamic Elements:

If the form elements are being added dynamically, using a loop can simplify the process. The following code snippet demonstrates how to add dynamic input elements with the appropriate array names:

for ($i = 0; $i ';
  echo '<input type="text" class="form-control" placeholder="Titel" name="levels[build_time][]">';
}

By using this method, PHP will automatically organize the input into an array structure without requiring manual indexing.

Additional Notes:

In the edited HTML, remove the original braces around "level" and "build_time" in the input names. This will result in an array structure where each index in the "level" and "build_time" arrays will correspond to the same level.
