PHP - Moved: Wp_dropdown_categories Generating Url Id Number Instead Of Slug

Hey guys,
I m not yet an experienced coder. SO faced alot of problems. Here, I'm trying to generate a UNIQUE RANDOM NUMBER set between two numbers. Repetative occurance must be avoided by all means as I want every number so generated bears a unique value. In other words, every values that made entry into the field of my database should be differant from each others.


<?php
$conN=mysql_connect("localhost","root","");
if(!$conN)
{
die('error'.mysql_error());
}
mysql_select_db("freebie_allusers",$conN);
$UIN=mt_rand(1,5);
$locateUIN="SELECT UIN FROM user_info WHERE UIN='".$UIN."'";
$fetchUIN=mysql_query($locateUIN);
$resultUIN=mysql_num_rows($fetchUIN);
if($resultUIN>0)
{



WHAT CODE IS REQUIRED HERE SO AS TO GENERATE UNIQUE RANDOM NUMBER?






}

else 
echo $UIN;
?>

Thanx in advance

Please i'm working on a project and i need to write a code that generates a unique random serial number.How can i go about it?

I need a way to generate a random number and insert into a database, and I need the database to not contain any duplicates of that number. I basically need to generate a RMA # (Return Merchandise Authorization Number), so the numbers absolutely CAN NOT be duplicate. I have no ideas how to go about this.

Should I generate a random number, search the database and see if there's a duplicate, and if there is re-run the script?

Hi, Im not sure whether this is a PHP or MySQL question, but im trying to get a select menu to only display the number of options that are defined in the mysql database.   For example   The code I have that retrieves the $quantity from the database.   Lets say that   $quantity = 3   Now I would like the option menu to only display three options, like this:

<select name="quantity">
<option value="<?php echo $quantity ?>"><?php echo 'Maximum of ' . $quantity . ' available'?></option>
<option value="1">1</option> 
<option value="2">2</option>
<option value="3">3</option>
</select>

but for example, if the $quantity was equal to 10 then I would like the menu to be displayed as such

<select name="quantity">
<option value="<?php echo $quantity ?>"><?php echo 'Maximum of ' . $quantity . ' available'?></option>
<option value="1">1</option> 
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
<option value="6">6</option>
<option value="7">7</option>
<option value="8">8</option>
<option value="9">9</option>
<option value="10">10</option>
</select>

How is it possible to do this? I am completely at a loss here.   Many Thanks   aquaman

Hi,

I have a trouble figuring out how to properly convert a list of product data from XML into CSV format.

My source is a XML file containing a list of products with attributes like color, size, material etc. with the following structu
Code: [Select]
    <?xml version="1.0" encoding="utf-8" ?>

                            </option>
                        </options>
                    </attribute>
                    <attribute>
                        <name>Material</name>
                        <options>
                            <option>
                                <name>Cotton</name>
                                <price>10.00</price>
                            </option>
                            <option>
                                <name>Polyester</name>
                                <price>0.00</price>
                            </option>
                        </options>
                    </attribute>
                </attributes>
            </product>
            <product>
                <name>Earrings</name>
                <price>29.00</price>
            </product>
        </products>
    </store>

Each product has a number of elements like name, price etc. but also a random number of attributes (like color, size, material etc.) that also have a random number of options.
Each option can affect the price of the product, so ordering a XS sized t-shirt can be cheaper than ordering a XL sized t-shirt.

I would like to end up with a CSV representing one attribute combination on each line.

In my example that would result in 3 colors x 5 sizes = 15 lines for the T-Shirt , 2 colors x 3 sizes x 2 materials = 12 lines for the Sweatshirt and 1 line for the Earrings without any attributes:
Code: [Select]
        name,price,color,size,material
T-Shirt,14.00,White,XS,
T-Shirt,14.00,Black,XS,
T-Shirt,14.00,Blue,XS,
T-Shirt,14.00,White,S,
T-Shirt,14.00,Black,S,
T-Shirt,14.00,Blue,S,
T-Shirt,19.00,White,M,
T-Shirt,19.00,Black,M,
T-Shirt,19.00,Blue,M,
T-Shirt,19.00,White,L,
T-Shirt,19.00,Black,L,
T-Shirt,19.00,Blue,L,
T-Shirt,24.00,White,XL,
T-Shirt,24.00,Black,XL,
T-Shirt,24.00,Blue,XL,
    Sweatshirt,49.00,White,XS,Cotton
Sweatshirt,49.00,Black,XS,Cotton
Sweatshirt,59.00,White,M,Cotton
Sweatshirt,69.00,Black,M,Cotton
Sweatshirt,69.00,White,XL,Cotton
Sweatshirt,69.00,Black,XL,Cotton
Sweatshirt,39.00,White,XS,Polyester
Sweatshirt,39.00,Black,XS,Polyester
Sweatshirt,49.00,White,M,Polyester
Sweatshirt,49.00,Black,M,Polyester
Sweatshirt,59.00,White,XL,Polyester
Sweatshirt,59.00,Black,XL,Polyester
Earrings,29.00,,,
   
I already managed to generate the CSV Output for simple products like the Earrings and products with just one attribute, but am struggling to come up with a way to generate all possible product attribute combinations for products with more than one attribute.

My miserable attempts at this so far have produced following code:

Code: [Select]
    <?php
    mb_internal_encoding("UTF-8");
    header('Content-Type: text/html; charset=utf-8');

    $source = "example.xml";
    $handle = fopen($source, "r");
    $fp = fopen('export.csv', 'w');
    $xml = simplexml_load_file($source);

    // Generate list of attributes (for csv header etc.)
    $header_attributes = array();
    foreach ($xml->products->product as $product) {
        if(isset($product->attributes)) {
            foreach($product->attributes->attribute as $attribute) {
                array_push($header_attributes, $attribute->name);
            }
        }
    }
    $header_attributes = array_unique($header_attributes);

    $csvheader = array(
        'name','price' // these exist for all products, could also include weight, image, description, special price etc...
    );

    $static_csvheadercount = count($csvheader);

    foreach($header_attributes as $attribute) {
        array_push($csvheader, $attribute); // add variable number of attribute fields to csv header
    }

    fputcsv($fp, $csvheader);

    foreach ($xml->products->product as $product) {  // loop through each product
        if(isset($product->attributes)) $simple = 0;
        else $simple = 1;
        if($simple == 1) { // if product is a simple product with no attributes
            $output=array();
            array_push($output,(string)$product->name);
            array_push($output,(string)$product->price);
            for($i = $static_csvheadercount + $attribute_position; $i < count($csvheader); $i++) {
                        array_push($output, '');
            }
            fputcsv($fp, $output);
        }
        else { // is a configurable product with attributes
            $json = json_encode($product->attributes);
            $attributes = json_decode($json, TRUE);
            $attributes_number = count($product->attributes->attribute);
            if($attributes_number > 1) { // if product has more than 1 attributes so we have to generate each attribute combination
                //
                // I'm trying to figure out what should happen here
                //
            }
            else { // if product has only one attribute
                $attributename =  (string)$product->attributes->attribute->name;
                $attribute_position = array_search($attributename, $header_attributes);
                $options_number = count($product->attributes->options->option);
                $pos = 1;
                foreach($attributes['attribute']['options']['option'] as $option) { 
                    $output=array();
                    array_push($output,(string)$product->name);
                    array_push($output,(string)$product->price);
                    for($i = $static_csvheadercount - 1; $i < ($static_csvheadercount + $attribute_position); $i++) {
                        array_push($output, '');
                    }

                    $output[$static_csvheadercount + $attribute_position] = $option['name'];
                    for($i = $static_csvheadercount + $attribute_position; $i < count($csvheader) - 1 ; $i++) {
                        array_push($output, '');
                    }
                    fputcsv($fp, $output);
                    $pos++;
                }
                $output=array();
                array_push($output,(string)$product->name);
                array_push($output,(string)$product->price);
                for($i = $static_csvheadercount; $i < count($csvheader); $i++) {
                    array_push($output, '');
                }
                fputcsv($fp, $output);
            }
        }
    }

    ?>
      
I've been stuck at this problem for hours unable to figure out a solution.

Can someone give a few tips or pointer how to achieve the output for products with multiple attributes?
