I create a login form in index.php and action of that form is loginform.php, so i want to functional the remember me checkbox in php.this
is loginform image
The original script
The form
> <form action="<?php echo $_SERVER['PHP_SELF']?>" method="post">
> Username: <input type="text" name="username" maxlength="40"> Password:
> <input type="password" name="pass" maxlength="50"> <input
> type="submit" name="submit" value="Log in"> </form>
An extremely simple login form with fields for a username, a password and of course a submit button. I should also mention at this point that for the sake of simplicity for this tutorial, I am using “PHP_SELF” (forms action code is contained within the same file) I would recommend keeping all of your scripts in separate files for actual development.
The php
For security reasons, and so that I don’t give away all of my secrets, I wont be sharing the entire login script here. If you are still reading this tutorial I assume you have a working knowledge of php and indeed, a login script that you are trying to improve upon, so this shouldn’t be a problem.
Once I have connected to my database and carried out all of my validation checks I proceed to log in a verified user using the following code:
$hour = time() + 3600;
setcookie('ID_my_site', $_POST['username'], $hour);
//then redirect them to the members area
header("Location:example-page.php");
Above I simply set two cookies lasting one hour each, one for username, and one for password, and redirect them to the members area.
Adding the remember me functionality
The form
Firstly, we need to actually provide our form with a remember me checkbox. Adding this makes our form look like this:
<form action="<?php echo $_SERVER['PHP_SELF']?>" method="post">
Username:
<input type="text" name="username" maxlength="40">
Password:
<input type="password" name="pass" maxlength="50">
<input type="checkbox" name="remember" value="1">Remember Me
<input type="submit" name="submit" value="Log in">
</form>
The php
Now we need to make this checkbox do something. Namely, when checked, remember the users username and place it in the username field on each of their corresponding visits to the login page. To do so, I decided to use cookies. I couldn’t use the “ID_my_site” username cookie that I set above, as this was being killed each time the user logged out. The solution was to create an additional cookie named “remember” which also stored the username, like so:
$year = time() + 31536000;
setcookie('remember_me', $_POST['username'], $year);
Above we have added this additional cookie, lasting for a year, so that when a user logs in it creates an additional cookie that holds the users username. However, at the moment, it is not being used. Changing:
<input type="text" name="username" maxlength="40">
to:
<input type="text" name="username" maxlength="40" value="<?php
echo $_COOKIE['remember_me']; ?>">
in our login form will now store this username into the text field for future visits:
We are not finished yet though. Currently, the code is storing this information for every user. We want it to remember only those users who specifically request this functionality. To do this, we run a simple check before we create the additional cookie. This check looks to see if the remember me checkbox has been checked, and only creates our new cookie if it has. Like so:
if($_POST['remember']) {
setcookie('remember_me', $_POST['username'], $year);
}
elseif(!$_POST['remember']) {
if(isset($_COOKIE['remember_me'])) {
$past = time() - 100;
setcookie(remember_me, gone, $past);
}
}
The above code also handles the scenario where a cookie is present, but the user has identified that they no longer want to be remembered, by seting any existing cookies to a time in the past, essentially killing them.
Further improvements
The above code does indeed achieve the main aim of this tutorial, to remember a users username in a log in form when they request it. However, to improve usability further, I wanted the checkbox to be automatically checked when a user has requested to be remembered, and unchecked when they haven’t. Adding this into our form gives us our final form code:
<form action="<?php echo $_SERVER['PHP_SELF']?>" method="post">
Username:
<input type="text" name="username" maxlength="40" value="<?php
echo $_COOKIE['remember_me']; ?>">
Password:
<input type="password" name="pass" maxlength="50">
<input type="checkbox" name="remember" <?php if(isset($_COOKIE['remember_me'])) {
echo 'checked="checked"';
}
else {
echo '';
}
?> >Remember Me
<input type="submit" name="submit" value="Log in">
</form>
How can i create a html form that action attribute have 2 destination.I want when user click on submit bottom , check if user entered wrong data the page goes to another pages with window.location and if user insert the correct input goes to main page with the same instruction.
First of all, what do you mean by correct input?
Main form data validation occurs in server side, not client side. you'd better use client side just for simple verification, like for typos.
There is no need for 2 destination pages (as you call it so).
You may use the standard action attribute which is the page on the server to which you are sending your form data.
there, You have the option to decide which condition needs what action and send the data (and then the user) to the desired page / action.
Sample code for the form
<form id='myform' action='action.php' method='POST' target='formresponse'>
<label for='name' >Your Full Name*: </label><br/>
<input type='text' name='name' id='name' maxlength="50" /><br/>
<label for='email' >Email Address*:</label><br/>
<input type='text' name='email' id='email' maxlength="50" /><br/>
<input type='button' name='Submit' value='Submit' />
</form>
<iframe name='formresponse' width='300' height='200'></frame>
Multiple action
function SubmitForm()
{
document.forms['contactus'].action='action1.php';
document.forms['contactus'].target='frame_result1';
document.forms['contactus'].submit();
document.forms['contactus'].action='action2.php';
document.forms['contactus'].target='frame_result2';
document.forms['contactus'].submit();
return true;
}
I have a form in a django site
<form method="POST" action="." class="right_custom">{% csrf_token %}
<br>{% trans "Enter the discount coupon code if you have any" %}</br>
<input type="text" name="coupon_code" size="25" maxlength="25" />
<input type="submit" name="submit" value="Caluclate Discount"/>
</form>
I would like to translate the entire site to a lot of languages. I need to translate the button text which is Caluclate Discount. How can I do that? if i use {% trans %} tag, how will the view catch the right post request?
UPDATE
There are many forms on the same page like this and my view uses if postdata['submit']=="Caluclate Discount" to determine which submit request it is.
I was able to get the translation working.
Thanks to the answers by #linux-warrior and #Joachim
Now the form is
<form method="POST" action="." class="right_custom">{% csrf_token %}
<input type="hidden" name="form_name" value="discount_form" />
<br>{% trans "Enter the discount coupon code if you have any" %}</br>
<input type="text" name="coupon_code" size="25" maxlength="25" />
<input type="submit" name="submit" value="{% trans "Caluclate Discount" %}" />
</form>
And i check for if postdata['form_name']=='discount_form' in my view
For buttons, you really don't use the value field for anything else than the button text, so it is straightforward to translate:
<input type="submit" name="submit" value="{% trans "Caluclate Discount" %}"/>
I think that you should use {% trans %} for submit "value". I don't understand why would you need that value inside your view. If you want, you can still give your submit input a custom "name" attribute.
Edit. By the way, your
<br>...</br>
thing inside your form appears to be a bug. You will probably want to make it
<p>...</p>
instead. It is also not recommended to use "submit" name for a type="submit" input (taken from http://api.jquery.com/submit/):
Forms and their child elements should not use input names or ids that conflict with properties of a form, such as submit, length, or method. Name conflicts can cause confusing failures. For a complete list of rules and to check your markup for these problems, see DOMLint.
Your view doesn't care about what is the submit button's value, so even if you translate it, your view function will work.
I'm trying to do some pretty basic form posts with Django, but whenever I try to click on the button to submit the information nothing happens. No errors or messages of any kind show up in terminal or in developer in Chrome. There is no JS on this page just straight html:
<form method="post" action="/">
{% csrf_token %}
<input type="text" id="name" name="name"/>
<input type="text" id="password" name="password"/>
<input type="button" value="Sign Up!"/>
</form>
My view for this page is pretty straightforward as well:
def sign_up(request):
return render_to_response('portal/signup.html', context_instance=RequestContext(request))
I'm really baffled as to what is going on, I've been following this to learn authentication. Everything works but I thought adding a "create user" would be a next step. I can't seem to get any form of any kind to work on other pages as well.
Any help would be great, I'm going crazy!
I think that your problem is that you're using
<input type="button" value="Sign Up!"/>
instead of
<input type="submit" value="Sign Up!"/>
the input submit will send all the form data to the server, the input button won't.

All,
There is a template say x.html
its contes are
<form action ="/lookinto/a">
<p >name:</td><td> <input type="text" id=name" name="name"></input></p></tr>
<tr><td>
<p >Section:</td><td> <input type="text" id="section" name="section"></input></p></td></tr>
</form>
My question is that when handling,/lookinto/a if i have an exception how to send the data back to x.html
i.e, if name is xx and while saving there is a error how is xx sent back to x.html from views.
Thanks......
Use Django's forms framework.
