No.

[Getting "failed to open stream: Permission denied", but I'm sure process is runn]

I'm getting this error when I try to fwrite to a directory:

failed to open stream: Permission denied

 

I have added the user www-data to the group which has permission to the directory?

 

The directory is this:

/home/directory1/documents

 

directory1 = drwxr-x---

documents = drwxrwx---

 

Does anyone know whats going on?

[If client submits value higher than X, then return false]

Lets say I have a MySQL value of 4... and I have a HTML INPUT field.. Is there a way to make it so that if a client tries to submit a value higher than 4, then they will be returned a message? Something like:

 

<SCRIPT type="text/javascript">
function validateForm() {
	if (document.forms["form"]["quantity"].value== (+$row['quantity']) {
		alert ("Cannot submit because the quantity specified is not available.");
		return false;
	}
}
</SCRIPT>
<INPUT name="quantity">

[trouble updating database from form]

Your welcome.

[Need help from a PHP accountant LOL]

Your right. Next time..

[trouble updating database from form]

I'm 99% sure its necessary in that case. Try it, see what happens. If still failure, check your servers error log to see what PHP says.

[How to find certain parts of text within a file?]

I normally don't suggest long shots but you've had a marathon of zero responses, so:

 

From my memory, PHP cannot get returned system verbose, but I could be wrong:

If your on Linux, try and get PHP to use a system command to return located text from a file.

[Need help from a PHP accountant LOL]

Going over the code 10 times is due diligence.

[trouble updating database from form]

In your Javascript..

 

<?php echo $r_admin ?>

should be

<?php echo $r_admin; ?>

[Need help from a PHP accountant LOL]

Yeah, I know I just noticed that.

 

Well, I went over the code about 10 times.

Please note: This is a help forum. Thanks.

[Need help from a PHP accountant LOL]

Whats wrong with this arithmetic code?

 

$sizestotal = $content['sizes'] * $row['price'];
$sizeltotal = $content['sizem'] * $row['price'];
$sizeltotal = $content['sizel'] * $row['price'];
$sizeltotal = $content['sizexl'] * $row['price'];
$idtotal = $sizestotal + $sizemtotal + $sizeltotal + $sizexltotal;
$total += $idtotal;

[unexpected T_STRING]

Mistake detected!

There was an extra

';

that should not have been there.

[unexpected T_STRING]

Yep, thats the exact code I used from the start. I suspect the error is else where:

 

 

<?php
	session_start();
if (empty($_SESSION['cart']['content'])) {
	echo '<DIV class="nocart">No product in cart.</DIV>';
}
else {
	echo '	<DIV class="cartcontent">';
		$link = mysql_connect('localhost', 'testusr', 'testpw');
		mysql_select_db('testdb', $link);
		foreach ($_SESSION['cart']['content'] as $content) {
		$query = "select * from products where id='{$content['id']}'"; $result = mysql_query($query); $row = mysql_fetch_array($result);
		echo '
			<DIV class="cartproduct">
				<DIV class="productdescriptor">
					'.$row['id'].'
					<BR>
					<IMG alt="" class="thumbnail" src="../products/'.$row['fordir'].'/'.$row['categorydir'].'/'.$row['id'].'/thumbnail.png">
				</DIV>
				<DIV class="cartproductdata">
		';
	';
					if ($content['sizes'] == 0) {goto sizem;} else {echo "<B>Small:</B> ".$content['sizes'];}
					echo "<BR>";
					sizem:
					if ($content['sizem'] == 0) {goto sizel;} else {echo "<B>Medium:</B> ".$content['sizem'];}
					echo "<BR>";
					sizel:
					if ($content['sizel'] == 0) {goto sizexl;} else {echo "<B>Large:</B> ".$content['sizel'];}
					echo "<BR>";
					sizexl:
					if ($content['sizexl'] == 0) {goto endsizes;} else {echo "<B>Extra large:</B> ".$content['sizexl'];}
					echo "<BR>";
					endsizes:
					echo '	<BR>
						<BR>
						<B>Unit price:</B> $'.$row[price].' AUD
						<BR>
						<BR>
						<INPUT type="submit" value="REMOVE FROM CART">
				</DIV>
			</DIV>
		';
		$sizestotal = $content['sizes'] * $row['price'];
		$sizeltotal = $content['sizel'] * $row['price'];
		$idtotal = $sizestotal + $sizeltotal;
		$total = $idtotal;
	}
	echo "	</DIV>";
	mysql_query ($query);
	mysql_close($link);
	echo '
		<DIV class="totalandproceed">
			Total: $'.$total.'
			<BR>
			<INPUT type="submit" value="PROCEED TO PAYMENT">
		</DIV>
	';
}

?>

[unexpected T_STRING]

Hey Buddski,

 

 

Not one of those lines worked - still getting the same error.

[unexpected T_STRING]

What is a T_STRING? google.com cannot find anything about it in the PHP manual.

 

... and, why am I getting "unexpected T_STRING" for this line?

if ($content['sizes'] == 0) {goto sizem;} else {echo "<B>Small:</B> '.$content['sizes'].'";}

[E-mail Form]

You all good?

[Equivalent of * in a $_SESSION?]

There is. I just re-wrote my code:

 

if ($_POST['size'] == "Small") {
if (isset($_SESSION['cart']['content'][$_POST[id]])) {
	$_SESSION['cart']['content'][$_POST[id]]['sizes'] += $_POST['quantity'];
} else {
	$_SESSION['cart']['content'][$_POST[id]] = array ('id' => $_POST['id'], 'sizes' => $_POST['quantity']);
}
} elseif ($_POST['size'] == "Large") {
if (isset($_SESSION['cart']['content'][$_POST[id]])) {
	$_SESSION['cart']['content'][$_POST[id]]['sizel'] += $_POST['quantity'];
} else {
	$_SESSION['cart']['content'][$_POST[id]] = array ('id' => $_POST['id'], 'sizel' => $_POST['quantity']);
}
}

[E-mail Form]

Yeah, you need to create a HTML form and name your INPUT accordingly:

<INPUT name="subject">

 

No, the client cannot see your PHP code. Web server software will not send it.

[Equivalent of * in a $_SESSION?]

I see. Do you mean something like this?:

 

$all = $_SESSION['cart']['content'][];
foreach ($_SESSION['cart']['content']['$all']['sizel'] as $content) {

[E-mail Form]

$from = $_POST['from'];
$subject = $_POST['subject'];
$body = $_POST['body'];
$header = 'From: Website form - $from';
mail(your@email.com, $from, $subject, $body, $header);

 

There.

[Equivalent of * in a $_SESSION?]

Is there an equivalent to * (any) in a $_SESSION? Something like this:

 

foreach ($_SESSION['cart']['content'][*]['Large'] as $content) {

[Different ways to write foreach]

No problem. Thanks, Nightslyr.

[Different ways to write foreach]

Is there a shorter way to achieve this in a single foreach()?

 

foreach ($_SESSION['cart']['content']['sizes'] as $content);
foreach ($_SESSION['cart']['content']['sizem'] as $content);
foreach ($_SESSION['cart']['content']['sizel'] as $content);

 

I am thinking something like:

foreach ($_SESSION['cart']['content']['sizes'] && $_SESSION['cart']['content']['sizem'] && $_SESSION['cart']['content']['sizel'] as $content);

or

foreach ($_SESSION['cart']['content'] = ['sizes'] || ['sizem'] || ['sizel'] as $content);

[$_SESSION field will not update]

Never mind. I have re-wrote the way entities are stored in the session. They are now stored as:

$_SESSION['cart']['content'][$_POST[id]][$_POST[size]] = array ('quantity' => $_POST['quantity'])

 

opposed to:

$_SESSION['cart']['content'][] = array ('id' => $_POST['id'], 'size' => $_POST['size'], 'quantity' => $_POST['quantity'])

 

EDIT: Well, this is flawed. But I will figure it out.

[$_SESSION field will not update]

Unfortunately, I spoke too soon. Now another problem has developed.

 

If I add an entity with a quantity of 1, and then add the same entity with a quantity of 1, I get a single entity with a quantity of 2, however,

If I add an entity with a quantity of 1, and then add the same entity with a quantity of 3, I get two entities - entity A/quantity-1 & entity A/quantity-3.

 

Why is this happening?
