how to send parameters from js to php codeigniter

Question

I don't know what i'm doing wrong and im stuck in this part of my project so any help would be appreciated

here is my html:

<form id="form_search" method="post" action="/controler/something">
<select id="tip_fam" maxlength="100" >
<option value="1">something 001</option>
<option value="2">something 002</option>
<option value="3">something 003</option>
<ul id="print" class="bot"><li>Print</li></ul>
</form>

JS:

$("#print").click(function(){
        url = base_url+"index.php/almacen/product/create_pdf/"+$("#tip_fam").val();
        window.open(url,'',"width=800,height=600,menubars=no,resizable=no;")
    });

Php (codeigniter) :

public function create_pdf(){       

    $tip_fam = $this->input->post('tip_fam');

i thought i could get the value of the select this way but when i print it in a var_dump(), it shows me "boolean false".

can't make a post with window.open ... need to submit form to _blank target, or use a get — charlietfl

Like what @charlietfl said, to access the post data you have to submit the form. What you're doing is just opening a new window. — kross

thanks for answering, i'm going to try as @charlietfl says but i'm wondering if there is a way to send parameters to that php function — Rildo Gomez

sure, as query string get params or codeigniter url segments — charlietfl

i think i didn't explain it properly. i have more than one button and i did a submit already so i thought opening a new window with js would submit the form but i was clearly wrong, do you have an example how i can do that please? — Rildo Gomez

to send value in url and to use in controller, you should capture that vales in parameter of the function. Change your code like this, it will work.

public function create_pdf($tip_fam){       

     echo $tip_fam;// will echo the value which you passed from view.

You don't actually have to use javascript. I would do it this way.

EDIT: You can have more than one submit button. Just check it in your function.

View:

<form id="form_search" method="post" action="/controller/something">

    <select id="tip_fam" maxlength="100">
        <option value="1">something 001</option>
        <option value="2">something 002</option>
        <option value="3">something 003</option>
    </select>

    <input type="submit" name="print" id="print" value="Print">
    <input type="submit" name="print" id="print" value="PrintAndSave">

</form>

Controller:

public function something()
{
    // Check which button was clicked
    $submit_button = $this->input->post('print');

    if( $submit_button == 'print' )
    {
        // Do print
    }
    elseif( $submit_button == 'printAndSave' )
    {
        // Do print and save
    }
}

i was trying to do it that way because i have more than one bottom and one of them is already using that action

kross Over a year ago

What do you mean by more than one bottom? You meant more than one button? Like you already have a submit button so this is another button?

Rildo Gomez Over a year ago
