variable assignment open_form() codeigniter

Question

just a simple question, can we assigned codeigniter open_form() to javascript var?

i have a code like this:

var openForm = '<?php echo form_open("controller/some_function", 
array('class' => 'class_name', 'enctype' => 'multipart/form-data'));?>';

but when i run it, i got error in my console saying:

Uncaught SyntaxError: Invalid or unexpected token

but, when i try this:

var closeForm = '<?php echo form_close(); ?>';

it didn't show any error.

though i guess it's not about syntax error, i still have no idea what is wrong and what happens. can anyone explain?

What you are trying to achieve here? Do you want dynamically append HTML or codeigniter form somewhere? — Shrikant Mavlankar

Yes. You can use like this

var openForm = `<?php echo form_open("controller/some_function", array("class" => "class_name", "enctype" => "multipart/form-data")); ?>`;

openForm += '<?php echo form_close(); ?>';

$("#your_element)id").html(openForm);

In javascript You can't split a string across multiple lines. <?php echo form_open(); ?> add \n at the end which create Syntax error.

As well <?php echo form_open(); ?> adds double quotes, which also ends into escaping issues.

To avoid issues In such cases you can use the template literals which is `

Yes. ` is called back-tick where as ' is called as single quote. Template literals are enclosed by the back-tick where as strings can be enclosed with single quote or double quote.
