The Form Helper

Form Open

Purpose: Generates form open tag for a form that is to be used for HTTP POST requests.

Arguments: Accepts up to three arguments:

• 1st Argument: $location - a string representing the location that you would like your form to be posted to.
• 2nd Argument (optional): $attributes - an array containing key value pairs that can be added to the form opening tags.
• 3rd Argument (optional): $additional_code - a string that can be added onto the end of the form tag.

For Example:

Let's assume that you are building a form for the following website URL:

http://www.your-site.com/members

Let's also assume that you wanted to build a form that is to initiate a POST request that is to be sent to:

http://www.your-site.com/members/submit

To generate form opening tags, we could use the following code inside of a view file:

<?php
echo form_open('members/submit');
?>

The above code will generate the following HTML:

<form action="http://www.your-site.com/members/submit" method="post">

PLEASE NOTE: The result above is made with the assumption that the BASE_URL is set to http://www.your-site.com/

Form Close

Purpose: Generate a simple form close tag.

Example:

<?php
echo form_close();
?>

The above code will generate the following HTML:

</form>

Form Input Helpers

The Trongate framework also comes with a rich assortment of form field helpers. The table below references all of the form field helpers that are available for use:

Form Buttons

The Form Helper also offers the following two helpers for generating form buttons:

<?php

echo form_open_upload('books/submit');

echo form_input('title', '');

echo form_input('author', '');

echo form_textarea('information', '');

echo form_submit('submit', 'Submit');

echo form_close();

?>

Form Open Upload

Purpose: Creates a form opening tag for uploading files. It accepts the same arguments as the Form Open helper, as explained above.

Example:

<?php
echo form_open_upload('members/submit_upload_picture');
?>

The above code will generate the following HTML:

<form action="http://www.website.com/members/submit" method="post" enctype="multipart/form-data">

PLEASE NOTE: The result above is made with the assumption that the BASE_URL is set to http://www.website.com/
