Freedom-n-Democrazy

Is there a way to make it How can I go about removing a $_SESSION entity if certain array values of it equal a specific value? I am thinking something along the lines of this: if (isset($_SESSION['cart']['content'][$_POST['id']])) = array ('sizes' => 0, 'sizem' => 0, 'sizel' => 0, 'sizexl' => 0) { // remove $_SESSION['cart']['content'][$_POST['id']] }

Hey guys, Nah I hadn't but someone from codingforums.com helped me out so I've got it all sorted. Thanks.

$carttotal = +$idtotal; EDIT: While this stopped the PHP notice, it made my calculation thing stop working.

I'm getting: ... for this: $idtotal = $sizestotal + $sizemtotal + $sizeltotal + $sizexltotal; $carttotal += $idtotal; Why?

Oh dear! I've spoken way too soon! The code isn't working properly yet. It only worked because I inserted double quotes around the PHP: if (document.forms["form"]["quantity"].value > "<?php $row['sizes'] ?>") ... but the PHP code still fails to produce the number as can be seen in the source code: if (document.forms["form"]["quantity"].value > "") I can confirm however that MySQL is working, as everything else that uses PHP-MySQL works. So, I think this is an issue with the way "<?php $row['sizes'] ?>" is being implemented. I can still say solved though because the JavaScript part has been fixed.

I solved it with a bit of help from Nightslyr and Old Pedant from codingforums.com. I was told I had to use the PHP-MySQL code before the JavaScript, as $row was undefined. I then found a couple of other problems myself where $id was not defined (which is the reason why PHP in the HTML stopped working earlier) and double quotes were not used around the PHP code in the JavaScript. The page now fully works! This problem is solved.

I have found one problem - the function validateForm() isn't even working. I'll look into this now and report back my finding. EDIT: The form is only not working because <?php $row['sizes'] ?> is producing nothing. When I replace <?php $row['sizes'] ?> with "3", the whole page works! So, the error lays in getting <?php $row['sizes'] ?> outputting.

I have placed the PHP-MySQL call code at every point before the JavaScript and it does not work, yet the PHP code <?php $row['sizes'] ?> continues to work when embedded in HTML. This tells me the PHP code has been implemented wrongly in JavaScript. Perhaps I need to brake out of JavaScript?

It comes out as blank, and when I use the same code after PHP calls MySQL, it works.. so, I placed the code where PHP calls MySQL before the JavaScript, then the PHP in the HTML stopped working. Whats the go with that?! Already done. The JavaScript code now sits at this in the bold: if (document.forms["form"]["size"].value=="Small") { if (document.forms["form"]["quantity"].value > <?php $row['sizes'] ?>) { alert ("Cannot submit because the quantity exceeds availability."); return false; } }

If you've started reading from the beginning of this thread, then you have probably got lost in what its actually about, so I will refresh: I am wanting to make it so if a client tries to submit a value in a HTML INPUT form that is higher than a specific value, then JavaScript will deny the form being submitted and return a message to the client. The value of which the number cannot go over will be variable and be pulled from a MySQL table. I am thinking the JavaScript and HTML portion of the code being something along the lines of this: So if you've got any ideas on how it can be achieved, then I would love to hear them.

My source is trashed from all the effing about on this forum. I'm leaving this website for a bit, restoring the file from backup, and then rebooting this thread. We've gone too deep. Wiping out this thread as though it never existed would be a good thing. im also gonna f off this facebook bull shit.

This is exactly why i told you several replies ago not to simply assume your code works. The syntax for a select query should be.... if ($result = mysql_query($sql)) { if (mysql_num_rows($result)) { // $result contains a valid resource object containing data } else { // no records found matching your query. Handle the error } } else { // your query failed. handle the error } Wheres this suppose to go?

I thought you meant the rest of the code - not related to this thread.

The source code: if (document.forms["form"]["quantity"].value = > ) { alert ("Cannot submit because quantity exceeds availability."); return false; } The value is not showing! Why! Do you want me to dump the entire source code into a CODE box?

I just tried this, but doesn't work either.. just submits: if (document.forms["form"]["quantity"].value = > <?php echo $row['sizes']; ?>) { alert ("Cannot submit because quantity exceeds availability."); return false; }

Ok, so does anyone know whats going on?

... and can some please ban this AyKay47 idiot. He constantly comes in and trashes my threads with his vomit.

Yeah, I don't care about best practices. I only care about trying to get this validation thing working - which is what this thread is about. People don't seem to be able to have a normal conversation. I am not here for a lecture of the way I code. I'm not replying to anything thats not on topic.

Can you guys please stop assuming and criticizing. If your not going to help, please get out: http://i55.tinypic.com/6qia1g.png

No, everything in the page works except for what I am discussing in this thread.

Sure, This is everything related to the script in regards to the quantity validation. <?php $link = mysql_connect('localhost', 'testusr', 'testpw'); mysql_select_db('testdb', $link); $query = "select * from products where id='$id'"; $result = mysql_query($query); $row = mysql_fetch_array($result); mysql_query ($query); mysql_close($link); ?> <SCRIPT type="text/javascript"> function validateForm() { if (document.forms["form"]["quantity"].value=="") { alert ("Cannot submit because a quantity has not been specified."); return false; } var integer = parseInt (document.forms["form"]["quantity"].value); if (integer > <?php echo $row['sizes']; ?>) { alert ("Cannot submit because quantity exceeds availability."); return false; } if (document.forms["form"]["size"].value=="") { alert ("Cannot submit because a size has not been selected."); return false; } } </SCRIPT> <FORM action="../../../../cart/addtocart.html" method="post" name="form" onsubmit="return validateForm()"> <DIV> Add <INPUT class="quantity" name="quantity" value="1"> <SELECT class="size" name="size"><OPTION>Small</OPTION><OPTION>Large</OPTION></SELECT> to <INPUT class="cart" type="submit" value="CART"><INPUT name="id" type="hidden" value="<?php echo $id; ?>"> </DIV> </FORM>

I tried this, but the page just went ahead and submitted: Javascript: function validateForm() { var integer = parseInt (document.forms["form"]["quantity"].value); $noavailability = $row['sizes'] + 1; if (integer > $noavailability) { alert ("Cannot submit because quantity exceeds availability."); return false; } } HTML <INPUT class="quantity" name="quantity" value="1">

I have narrowed the problem down to an operating system problem. Thanks.

When I login as www-data I can write to the path fine. Why won't Apache do it? Apache is running as root > www-data. <?php $fp = fopen("/home/directory1/Documents/feedback.txt", "a"); fwrite($fp, "".$_POST['feedback']." - ".$_SERVER['REMOTE_ADDR']."\n"); fclose($fp); echo "Done."; ?>
