How to Pass Array Through Hidden Field

Passing an array using an HTML form hidden element

Use:

$postvalue = array("a", "b", "c");
foreach($postvalue as $value)
{
    echo '<input type="hidden" name="result[]" value="'. $value. '">';
}

And you will get $_POST['result'] as an array.

print_r($_POST['result']);

Is it possible to pass an array in a form as a hidden field?

You can pass the id of the parent job in the hidden field, on form submit action you can get the parent id and retrieve the information of that job.

<input type="hidden" name="parent_job_id" value="<?php echo $jobId; ?>">

Make sure which index holding the id of the parent job.

It seems $job is an array, you can not echo it, you can echo its index.

Passing a multidimensional array through hidden input via POST

You just need to encode array to json and decode it on action page

echo '<input type="hidden" name="itemsArr" value="'.json_encode($itemsArr). '">';

And at your action Page just decode it

$itemsArr = json_decode($_POST['itemsArr'],true)

pass php multidimensional array from html hidden field to php

finally after trying lot of method this one worked for me with using serialize and unseiralize.

HTML:

<input type="hidden" name="data" value="<?php echo htmlspecialchars(serialize($data)) ?>">

PHP:

$excel = unserialize($_POST["data"]);

How to pass php array in input type hidden in html form

If I'm understanding you correctly, you can try this:

<form method="post" action="next.php">
 <input type="hidden" name="my_form_data" value="<?php echo htmlspecialchars(serialize($my_arr)) ?>">
 <button name="submit_btn">Submit</button>
</form>

Then in next.php you unserialize to get the PHP data structure back:

<?php
$my_arr = unserialize($_POST["my_form_data"]);

Passing array to hidden input and retrieve array with elements on different indexes

You can do that in PHP with the function explode. What this function does is split a string into an array by delimiter so in your case, add:

$array = explode(',', $arrayThatHasTheString[0]);

Pass array of objects as hidden field value into mvc controller

@FrenkyB You could change the binding to be a string and then digest it into a list like this.

public void Test(int celo, string pispis, string userji)
{
    var myList = JsonConvert.DeserializeObject<List<User>>(userji);

    //stuff
}

Javascript - Storing array of objects in hidden field

You can parse your array into a JSON-string to store it:

.push() is a function, therefore it needs () and not the [] array-syntax.

var elems = [];
elems.push('1');
elems.push('2');
elems.push('3');

$('#input_hidden_field').val(JSON.stringify(elems)); //store array

var value = $('#input_hidden_field').val(); //retrieve array
value = JSON.parse(value);

To create an object just change the definition of elems and the storage of the values:

var elems = {};
elems[0] = '1';
elems[1] = '2';
elems[2] = '3';

Demo

Reference

.stringify()

.parse()
