How To Enforce Minimum Qty

View Content

Here's the scenario....

A Customer clicks on a product on the product page, this will open up the page for the individual product.
In this example, it's a shirt.

The shirt is available in many sizes and colors. The Minimum QTY for this product is : 12 .
The customer can select as many sizes and colors as they want, as long they select a total of 12 (all sizes + all colors = total).

After making their selections for this shirt, there is an "Add to Cart" button.

I would like to run a check to make sure that the total is equal to or greater than the minimum QTY.

Here is the form :
Code: [Select]
<?php

Help!! How To Add A Minimum $i Counter Instead Of Maximum??

Similar Tutorials

View Content

ok here is my code:
it has a counter variable $i at the start which basically acts as a maximum cutoff for how much data can be output. i have this variable set at 5.

how can i make it so that it doesnt cut off the results (outputs the full 7 days worth of results if available), but ALWAYS outputs a minimum of 5 results?

$now = $now-(7*24*60*60); // Display 7 Days of Results
$query = mysql_query("SELECT * FROM table WHERE date >= '$now' ORDER BY max(date) desc");
$i = 0;
while ($row = mysql_fetch_assoc($query)) {
$cid = $row['cat_id'];
$title = $row['name'];
$seoname = cleanurl($title,0);

$img = 'images/'.$seoname.'.jpg';
if (!file_exists($img)) {
$img = '';
} else {
$img = 'images/'.$seoname.'.jpg';
}

if (!empty($img)) {
$i++;
}

if (!empty($img) && $i <= 5) { // Always show ATLEAST 5 results
echo '<img src="'.$img .'" style="width:528px;" alt="" />' . "\n";
}
}

Please help and look at my code..thanks.

Find Minimum In Array Loop Until...

Similar Tutorials

View Content

I need help this problem seem too tricky for me right now.

I got an array with decimal numbers and behind it says Yes/No. The min() function works magically and still is able to correctly give me the lowest value.
But how do i make a while loop that loops until it pops a value that is lowest and has Yes behind it?

For example:

Array => ('11,64|No', '209,81|Yes', '533,42|Yes', '27,90|No', '93,01|Yes')

So this function should return '93,01|Yes'

Tree Recursion

Hi,

I wrote a piece of code for doing a recursive printing of all the leaf nodes.

But it is not moving beyond one or two levels.

Here is the code:

$root = array(
"paa" => array (
"adi1" => array (
"cir1" => array (
"aka",
"ra", "vinodh","dkido"
),

"cir2" => array (
   "muta",
"la"
),

"cir3" => array (
"ezut",
"telAm"
),

"cir4" => array (
"ati"
)
),

"adi2" => array (

"cir1" => array (
"paka",
"vaV"
),

"cir2" => array (
"mutaR",
"RE"
),

"cir3" => array (
"ula",
"ku"
)
)
                )
            );

function traverse($ar)
{

foreach($ar as $key=>$value)

          {

echo "inside loop of ".$key."<br/>";

if(is_array($value))
{
    return traverse($value);
}

else

{
     echo $key."==>".$value."<br/>";
}

   }

}

traverse($root);

The output I get is:

inside loop of paa
inside loop of adi1
inside loop of cir1
inside loop of 0
0==>aka
inside loop of 1
1==>ra
inside loop of 2
2==>vinodh
inside loop of 3
3==>dkido

It does not seem to visit the other nodes.

Anything I missed here ?
