Send array values in PHP form - php

Question

I have a HTML form with embedded PHP code that creates a checkbox for each value contained in an array. Just like this:
<?php
$rows = array_map( 'str_getcsv', file( 'file.csv' ) );
$header = array_shift( $rows );
foreach ( $rows as $row ) {
echo '<input type="checkbox" id="'.$row[0].'" name="'.$row[0].'">
<label for="'.$row[0].'">'.$row[0].'</label>
<input type="number" name="'.$row[0].'" placeholder="Some text">';
}
?>
Now, I want to send this form using this code, which is inserted into another PHP file:
<?php
if( isset( $_POST ) == true && empty( $_POST ) == false ) {
$account = $_POST['account'];
$investment = $_POST['row[0]'];
$password = $_POST['password'];
$formcontent=" Account: $account \n $row[0]: $investment \n Password: $password";
$recipient = "my#email.com";
$subject = "My Form";
$mailheader = "From: My Form <my#form.com>";
mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");
echo "Some text";
}
?>
But it doesn't work. When you click on submit button the form does nothing.
I've checked it with success with HTML-only code, so I guess I'm making a mistake with PHP.
For those interested, here's a link to my form: Example
EDIT: I've removed preventDefault, as pointed by #DavidJorHpan, but I'm still stuck. I'm unable to make my form.php send $row[0] to my email.

Answer 1

Because you use preventDefault so it will never submit form until you code for submitting form
$("button").click(function(e) {
e.preventDefault();
});
You can remove that code or add code like
$('form').submit();

Answer 2

As David JorHpan pointed out in the second answer, you've got to remove preventDefault() from the button click event. That prevents the form from being submitted.
For every checkbox you have a corresponding number input field. Although possible, its not a good practice to have spaces in your 'name' attribute values. Try replacing those spaces with dashes or underscores. For example you can do something like below:
name="'.str_replace(' ','_',$row[0]).'"
and same can be done to id attribute values.
Your form submit check should work but it will make more sense if you change that as follows:
if($_SERVER['REQUEST_METHOD'] == 'POST')
{
// process here
}
After doing these changes try loading the page and see how it goes.
