Appending a string in a foreach loop

[HanneSThEGreaT]

Hello.

 

I'm trying to append the loop keys and values into a string and store it into a hidden field.

 

This is the code I have :

 

if (isset($_POST['ordered'])) {
// We can assign $_POST['product'] to a variable to make it easier to type out
$prod = $_POST['product'];
// Throw a little intro to see how many they checked
echo 'You selected ' , count($_POST['ordered']) , ' products.';
// Now we loop through it and get the IDS that were selected
// Foreach lets you select the $key and the $value for each iteration of the loop //

$strOrder = "";

foreach ($_POST['ordered'] as $key=>$id) {
	echo '<p/>
	ProdName: ' , $prod[$id]['name'] , '<br/>
	ProdPrice: ' , $prod[$id]['price'] , '<br/>
	ProdQty: ' , $prod[$id]['qty'] , '
	<hr/>';

	$strOrder .= $key . " " . $id;

	$TOT += $prod[$id]['price'] * $prod[$id]['qty'];

}

	$TOT2 = $TOT + 55;

	echo	'<input type="hidden" Name="TOT" value ="'. $TOT .'">';
	echo	'<input type="hidden" name="TOT2" value =". $TOT2 .'">';

	echo 	'<input type="hidden" name="Order" value=". $strOrder . '">';
}

 

strOrder does not get set to a value.

check the output of

 

print_r($_POST)

 

to make sure data is being passed first of all.

It does return everything posted

I'm suprised you're not getting any errors. what happens if you change it to this?

foreach ($_POST['ordered'] as $key=>$id) {
	echo '<p/>';
	echo "ProdName: {$prod[$id]['name']}<br/>";
	echo "ProdPrice: {$prod[$id]['price']}<br/>";
	echo "ProdQty: {$prod[$id]['qty']}<hr/>"; //not sire what <hr/>  is but i'm sure you have a reason for it
	$strOrder .= $key . "," . $id.";";
}
echo "strOrder String == $strOrder";

I get this echo 'ed :

 

strOrder String == 0,2;1,11;2,20; 

[Muddy_Funster]

well $strOrder is getting assigned values from the array using that, so just change the echo "strOrder String == $strOrder"; to your original code and you should be good to go. 

[HanneSThEGreaT]

I'm afraid I don't understand.

 

It seems as if the array indexes are stored into strOrder in stead of those indexes' values. I need the values inside the Order hidden field.  I am very dumb, and very new to PHP, but you guys have made my learning experience fun

[Muddy_Funster]

it's storing both:  strOrder String == 0,2;1,11;2,20;  the array index is the number before the , and the value of that index is the number between the , and the ;

 

what I think you want is

$strOrder .= $id." ".$prod['$id']['name'];

 

If I'm wrong show me an example of what you expect $strOrder to look like.

[HanneSThEGreaT]

Hello again. That gives me the indexes as well. I am stupid, way past stupid actually.

 

I'm looking for something similar to :

 

ProdName: Anti Stretchmark Cream
ProdPrice: 40.00
ProdQty: 3 

ProdName: The New Me Combo Pack 6
ProdPrice: 160.00
ProdQty: 3 

 

I also tried the impldoe method :

 

	$strOrder = "";

foreach ($_POST['ordered'] as $key=>$id) {
	echo '<p/>
	ProdName: ' , $prod[$id]['name'] , '<br/>
	ProdPrice: ' , $prod[$id]['price'] , '<br/>
	ProdQty: ' , $prod[$id]['qty'] , '
	<hr/>';


//	$strOrder .= $key . "," . $id.";";

	$strOrder .= $id." ".$prod['$id']['name'];
	$strOrder .= $id." ".$prod['$id']['price'];
	$strOrder .= $id." ".$prod['$id']['qty'];

	$TOT += $prod[$id]['price'] * $prod[$id]['qty'];

}

	$strOrder2 = implode(",",$strOrder);

	$TOT2 = $TOT + 55;

	echo	'<input type="hidden" Name="TOTALH" value ="'. $TOT .'">';
	echo	'<input type="hidden" name="TOTAL2H" value ="'. $TOT2 .'">';

	echo 	'<input type="hidden" name="Order" value="'. $strOrder2 . '">';
}

 

But it gives me an empty string. I just need a way to get the orders displayed. I get the indexes, but I do not know how to get those indexes' values

If you are trying to post the string to the email form (from the other thread), you can always just send exactly what is displayed on this page.

if (isset($_POST['ordered'])) {
$prod = $_POST['product'];
echo 'You selected ' , count($_POST['ordered']) , ' products.';
$strOrder = '';
foreach ($_POST['ordered'] as $key=>$id) {
	$strOrder .= '<p/>
	ProdName: ' . $prod[$id]['name'] . '<br/>
	ProdPrice: ' . $prod[$id]['price'] . '<br/>
	ProdQty: ' . $prod[$id]['qty'] . '
	<hr/>';
	$TOT += $prod[$id]['price'] * $prod[$id]['qty'];
}
// After the loop just echo the string and also send it in the form //
echo $strOrder;
$TOT2 = $TOT + 55;
echo '<input type="hidden" Name="TOT" value ="'. $TOT .'">';
echo '<input type="hidden" name="TOT2" value ="'. $TOT2 .'">';
echo '<input type="hidden" name="Order" value="'. $strOrder . '">';
}

Remember that those hidden fields MUST be inside a form for them to be sent across.

Just did that now and it works!

 

Thanks, now I have a lot of info to study!

 

You guys are the best! Hopefully one day, I'll get there with PHP
