Javascript and Php (MVC)

Question

i'm creating my own MVC Framework. I have a basic form in my view

<form action="?" method="post" >
    <input type="hidden" name="envoie" value="envoie" />
    <?php dico('INSCRIPTION_NOM'); ?><input id="name" type="text" name="name" /><br />
    <?php dico('INSCRIPTION_EMAIL'); ?><input id="email" type="text" name="email" /><br />
    <?php dico('INSCRIPTION_PWD'); ?><input id="pwd" type="password" name="pwd" /><br />
    <input type="button" value="<?php dico('INSCRIPTION_SINSCRIRE'); ?>" onclick="verifForm(document.getElementById('email').value);"/>
</form>

when I clock on the button they have a javascript function like that :

function verifForm(email) {
    var url ="?c=Inscription&a=VerifForm&email="+email;
    $.get(url, function(data){
        alert('resultat == '+data);
    });
}

Inscription was my controllers and VerifForm an method of the controller. email was the value of a input.

The Php function was :

public function actionVerifForm() {
        echo "OK";
}

When i click on the button i have all the code of the page on my alert but i only want the message "OK".

Thanks for helping me

what do you mean by i have all the code of the page on my alert? you mean your PHP code is alerted? — Joseph

You can test my appl on iftp.axioweb.fr/?c=Inscription&a=Formulaire for seeing the problem of the alert message — user1152762

what you are doing is AJAX, am i right? the data parameter IS your result. AJAX returns the echo-ed page as a string. if you mean to place it in the page, try jQuery .html() or .text() for a text only, escaped version.

function verifForm(email) {
    var url ="?c=Inscription&a=VerifForm&email="+email;
    $.get(url, function(data){
        $('#container-id-here').html(data); //html insert
        $('#container-id-here').text(data); //text insert
    });
}

and in your PHP, since you are doing AJAX, you should only echo what you need returned, and not the whole HTML mark-up (which means no <html><head>...</head></html>

it's working properly actually. the problem is that your PHP is not just echoing the result, but is including the HTML mark-up as well! the php should only echo what you want in order to return what you need.

if you are creating an MVC and this is your default view, you should also create an additional "ajax-only" view, with no additional HTML mark-up.
