Hi guys, I was wondering if it is possible to like a page on facebook through a checkbox, instead of using the FB like function/script. In other words; people fill out a form and can check the box if they like the page, such as: <?php if (isset($_POST['form'])) { if (isset($_POST['facebook_checkbox'])) { //like page } else{ //don't like } } ?> <form action="<? $_SERVER['PHP_SELF'];?>" method="post"> <input type="checkbox" id="facebook_checkbox" name="facebook_checkbox" /> <input type="submit" name="form" /> Is there any possibility to do that? Thanks in advance.

It is actually part of a quite large order form. Nevertheless I really appreciated your assistance! Thanks again for all yr time! Robbert

well actually since i have a very "large" form and i wanted to know if i really needed to edit all code that was already present.. I do understand your solution now though..

ok thanks, thus if i implement my own custom form validation, it is all good?

Sorry to bother you once more, I am trying to understand the code.. Why did you not use the if(isset($_POST['btn'])) function? Is that some outdated code or? Anyway, while i was trying to understand the code, I deleted some code to see what exact function it fulfills. I found that the code below, actually does what it should.. thus i was therefore wondering if you could please further explain your given solution.. See the script live here: http://www.maakmijnportret.nl/test3.php <?php session_start(); if (isset($_POST['position']) && !empty($_POST['position'])) { $_SESSION['position'] = $_POST['position']; } if (isset($_POST['name']) && !empty($_POST['name'])) { $_SESSION['name'] = $_POST['name']; } if (isset($_POST['newsletter']) && !empty($_POST['newsletter'])) { $_SESSION['newsletter'] = $_POST['newsletter']; } $name = $_SESSION['name']; $position = $_SESSION['position']; $newsletter = $_SESSION['newsletter']; if(!isset($_POST['btn']) && !isset($_POST['overview'])) { ?> <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post" enctype="multipart/form-data"> <input type="text" value="<?php echo $position; ?>" name="position" /> <input type="checkbox" class="styled" name="newsletter" value="on" <?php if($newsletter == 'on') { echo "checked";} ?> /> <input type="submit" name="btn" /> </form> <?php session_destroy(); } if(isset($_POST['btn'])) { ?> <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post" enctype="multipart/form-data"> <input type="text" value="" name="name" /> <input type="submit" name="overview" /> </form> Go <a href="<?php echo $_SERVER['PHP_SELF']; ?>?backto=position">back</a> <?php } if(isset($_POST['overview'])){ echo $position; echo $name; if($newsletter == 'on') { echo "Newletter on!"; } echo 'Go <a href="'. $_SERVER['PHP_SELF'].'">back</a>'; } ?> Thanks again, Robbert

Works great! except the "reset" function at the end gives an error: Warning: session_destroy() [function.session-destroy]: Trying to destroy uninitialized session in /home/musicv/public_html/maakmijnportret.nl/test3.php on line 49 is that just a warning or a bug? Thanks, learn a lot;)

done, one question though; is it also possible to go back in the session. Thus let's say you're here if(!empty($position) && empty($name)) and you want 1 step back in the form, for instance to uncheck the box, is that possible to implement or? Thanks again, Robbert

Thank you sooo much! works like a charm. I will follow up your advice Grts, Robbert

Sorry, one more question. Is there any way to (dubble) check if the checkbox is checked or not, everytime the form submits? For instance, if i check the checkbox, submit the form, go back and uncheck the checkbox.. it will stay checked in the session. Try my script at: http://www.maakmijnportret.nl/test3.php <?php session_start(); // start up your PHP session! if (isset($_POST['position'])) { $_SESSION['position']=$_POST['position']; } if (isset($_POST['name'])) { $_SESSION['name']=$_POST['name']; } if (isset($_POST['newsletter'])) { $_SESSION['newsletter']=$_POST['newsletter']; } $name = $_SESSION['name']; $position = $_SESSION['position']; $newsletter = $_SESSION['newsletter']; // eerste formulier if(!isset($_POST['overview']) && !isset($_POST['btn'])) { ?> <form action="<? $_SERVER['PHP_SELF'];?>" method="post" enctype="multipart/form-data"> <input type="text" value="" name="position" /> <input type="checkbox" class="styled" name="newsletter" value="on" <? if($newsletter == 'on') { echo "checked";} ?> /> <input type="submit" name="btn" /> </form> <?php } // form 2 if(isset($_POST['btn'])) { ?><form action="<? $_SERVER['PHP_SELF'];?>" method="post" enctype="multipart/form-data"> <input type="text" value="" name="name" /> <input type="submit" name="overview" /> </form> <?php } if(isset($_POST['overview'])) { echo $position; echo $name; if($newsletter == 'on') { echo "testing"; } } ?> Once the checkbox is checked, "testing" will keep showing up. Thanks again!

you seem to be right Thanks a lot!

The code you gave is similar to mine. But i have another statement: <?php session_start(); if (isset($_POST['newsletter'])) { $_SESSION['newsletter'] = $_POST['newsletter']; $newsletter = $_SESSION['newsletter']; } if($newsletter == "yes") { $newsl = 1; } //later in the code i use an if statement if($newsl == "1"){ echo"example"; } ?> When i put $newsletter = $_SESSION['newsletter']; outside the }, the word "example" will be echoot no matter if i checked the checkbox or not.

hmm although the problem is now that he does not save $newsletter to be used in a later stadium of the contactform right? When i trie to echo $newsl nothing comes up.. Is it possible to bypass that? Thanks again.

hmm thanks a lot, i placed $newsletter = $_SESSION['newsletter']; outside the } . When i place it inside the } it works! Thanks again:)

i am very sorry.. Forgot that too, have it in my original code... I actually expected that the code i "improvised" was not good at all, but that is not the case?

Hi there, Sorry forgot that in the code above, have it in my original code though.. Thanks for your reply! Robbert
