PHP - Check Box - Remove All Selected Items

When I remove 1 session item using this it works fine when I select more than 1 item to be removed I get unexpected results, I have checked the outputted html to see what positions get echoed into the remove check box and they are correct, so I guess the problem lies in my remove code

here is the part of the form that sends the remove check box

<?php 
for ($basket_counter=0;$basket_counter<$_SESSION['ses_basket_items'];$basket_counter++) {
   $price=sprintf("%01.2f",$ses_basket_price[$basket_counter]);
    $quantity=$ses_basket_amount[$basket_counter];
$code=$ses_basket_stockcode[$basket_counter];
$itemID=$ses_basket_id[$basket_counter];
    $name=$ses_basket_name[$basket_counter];
$image=$ses_basket_image[$basket_counter];
$size=$ses_basket_size[$basket_counter];
$sizechoice=$ses_basket_sizechoice[$basket_counter];
// create array from sizes and make the option box selections
if ($sizechoice!="" && (!in_array($sizechoice, array('One Size', 'one size', 'free size', 'Free Size', 'Adjustable', 'adjustable')))) { 
// add size trigger
$sizelist="add";
//create the array
$sizepick=explode(",", $sizechoice);
} else { $sizepick=$sizechoice; }
// adjust gst for AU customers
if ($country=='AU') { $price=sprintf("%01.2f",($price*1.1));
$unit=sprintf("%01.2f",($price/$quantity));
 }
else
{ $unit=sprintf("%01.2f",($price/$quantity)); }
?>
<tr>
  <td align='center' class='rescon' style="border-bottom:solid #330000 1px;"><input type="checkbox" name="remove[<?php echo $basket_counter; ?>]" value="<?php echo $basket_counter; ?>" /></td>


and here is the part of the code that processes the removal of the items

$remove = $_POST['remove'];
if (isset($remove) && ($remove!='')) {
        foreach($remove AS $key => $remove_position){
array_splice ($ses_basket_name, $remove_position, 1);
array_splice ($ses_basket_amount, $remove_position, 1);
array_splice ($ses_basket_price, $remove_position, 1);
array_splice ($ses_basket_stockcode, $remove_position, 1);
array_splice ($ses_basket_image, $remove_position, 1);
array_splice ($ses_basket_size, $remove_position, 1);
array_splice ($ses_basket_sizechoice, $remove_position, 1);
array_splice ($ses_basket_id, $remove_position, 1);
$_SESSION['ses_basket_items']--;
}
}


I am using a form with checkboxes named remove[$remove_position] and the positions in the form are correct for each item in the array, but when I select more than 1 item to delete they are not always the correct items only the first 1 selected.
What am I doing wrong here??

I have users in my database with many stored points ie age, gender, interests etc. about 20 points in all.   I have a table of products that I want to recommend only applicable products. They each have saved like minage, maxage, gender, interest etc for the ideal consumer. ie dress gender=f   This is the bare bones of what I have so far:

$result = mysql_query("SELECT * FROM user_table WHERE hash='$session_id'");
$rowuser = mysql_fetch_array($result);

$result = mysql_query("SELECT * FROM products");
$rowproducts = mysql_fetch_array($result);

So now I have $rowuser['gender'] = m , how do I remove all from $rowproducts where gender = f?   Is there a best way to do this knowing I have about 20 points to go through before I am left with an array with just the best selection of products for this user in it?

I have a form that has a section where you can pick multiple check boxes and when the info is returned to me it has the word Array at the end of it.

There are 2 check boxes on the form one fo Steve and one for Ben

Below is the code I am using in my PHP file

foreach($_POST['TestGroup'] as $val)
{
   echo $val . "\n";
}

The output from the PHP code is----Steve Ben Array.------

How do I keep Array from coming up?
 

I have this loop on a shorturl website i own that selects domains from my website and lists them in a dropdown list where users can select one domain to use as url shortener.

The problem is that when a users selects and entry from the dropdown list this created only the [[[main_url]]] entry from the database table bellow can be used. When someone selectes "coolartistname.site.com the submit button cannot be pressed. in other words it's not adding the SELECTED attribute other than the [[[main_url]]] domain.

Can anyone see on the code bellow why this would happen?

When i echo $shortUrlDomains it's just saying "Array" and $_REQUEST['shortUrlDomain'] shows nothing.

**Index.php**

    // get base urls
    $shortUrlDomains = getShortUrlDomains();
    
        <?php
        foreach ($shortUrlDomains AS $k => $shortUrlDomain)
        {
        
            // active domains only
            if (($shortUrlDomain['premium_only'] !== '1') && ($shortUrlDomain['premium_only'] !== $Auth->id))
            {
                continue;
            }
        
            echo '<option value="' . (int)$k . '"';
        
            if (isset($_REQUEST['shortUrlDomain']))
            {
                if ($k == (int)$_REQUEST['shortUrlDomain'])
                {
                    echo 'SELECTED';
                }
            }
        
            echo '>';
        
            echo $shortUrlDomain['domain'];
        
            if ($disabled == true)
            {
                echo ' (' . safeOutputToScreen(t('unavailable', 'unavailable')) . ')';
            }
        
            '</option>';
        }
        echo '</optgroup>';
        ?>

FUNCTIONS.PHP

    function getShortUrlDomains()
    {
        // if we already have it cached
        if(defined('_SETTINGS_SHORT_URL_DOMAINS'))
        {
            return unserialize(_SETTINGS_SHORT_URL_DOMAINS);
        }
        
        // get connection
        $db  = Database::getDatabase(true);
        
        // load from database
        $domains = $db->getRows("SELECT id, domain, premium_only, status FROM url_domain ORDER BY premium_only ASC, id ASC");
        
        // organise and replace site url
        $rs = array();
        foreach($domains AS $domain)
        {
            if($domain['domain'] == '[[[main_url]]]')
            {
                $domain['domain'] = _CONFIG_SITE_FULL_URL;
            }
            $rs[$domain{'id'}] = $domain;
        }

**MYSQL DATABASE**

    url_domain (id, domain, premium_only, status, date_created, owner) VALUES
    (1, '[[[main_url]]]', 0, 'enabled', '2019-03-02 08:13:00', 1) 
    (14, 'coolartistname.site.com', 6, 'enabled', '2020-04-18 19:21:59', 6);

 

First problem fixed.
My second problem is if the result is 0X.XX,0 or 0X.XX,1 I would like to remove the first 0
The X.XX are numbers, but the 0 is not always there.

Can anyone help please
Thanks

Hi all,

I have a html drop down menu and want to show the initially selected value as the one stored in the mysql database that a member selected.

I have 180+ rows in mysql that a member could have selected and would like to basically do this:

IF (value of option == $row['value'] ) { echo "selected=\"selected\"; }
I could put this in every one of the rows it would be much better to have an if statement. As there are so many values I do not know where to begin.

Can someone point me in the right direction?

Thanks

How can I select the last 5 db items? I was thinking a timestamp or some thing.

Code: [Select]
<?php
// first number
$first = $row['id'];
// second number
$second = 4;

//checking if the first number is muliple of second. If true then display ads.
If($first % $second == "0") {
echo 'ads to display';
}

It will work if i list items in correct order. Please let me know correct solution.
Thanks in advance !

What is the best way to capture items that someone wants to purchase when they don't have an account yet?

And I prefer not using cookies.

Hi,

i have had some help from these forums building a shopping cart system and i can add items to cart, empty cart but i need some help on how to update quantities.

Here is the code i use to add items

Code: [Select]
$pid = $_POST['prodid'];
$q = $_POST['qty'];

if(array_key_exists($pid, $_SESSION['cart']))
{
$_SESSION['cart'][$pid]=$_SESSION['cart'][$pid]+$q;
}
ELSE
{
$_SESSION['cart'][$pid]=$q;
}
Im displaying my items in a table with a text field for quantities which can be changed then click update. i see there is 2 things i need to do, first is to somehow create a loop for all the items in my table, i have no clue where to start on that, and then in that loop i have my update command.

im assuming the code to update would be something like

Code: [Select]
$_SESSION['cart'][$pid]=$_SESSION['cart'][$pid][$qty]
where $qty is the value of the text box in my table.

Any help would be appreciated.

Hi,

I'm having trouble carrying items between two files. The problem is that it works too well. Whenever I include a php file that echos something, the other php files echos the same thing. What are some ways to stop this, but still have access to the variable.

Thanks,
GEORGE

I have an array of products. The array has an ID and price. I'd like to know the most efficient way of adding up all the same ID fields in the array.

Code: [Select]
<?php
$items[] = array(
'id' => 1,
'price' => 5.99,
);
$items[] = array(
'id' => 2,
'price' => 1.99,
);
$items[] = array(
'id' => 3,
'price' => 2.40,
);
$items[] = array(
'id' => 2,
'price' => 6.99,
);
$items[] = array(
'id' => 4,
'price' => 8,
);
$items[] = array(
'id' => 2,
'price' => 3,
);
$items[] = array(
'id' => 3,
'price' => 1,
);

function add_like_items($items)
{
//manipulation

return $sums;
}

//$sums would be an array like 
//$sum[1] = 5.99
//$sum[2] = 11.98
//$sum[3] = 3.40
//$sum[4] = 8 

?>
Anybody have suggestions on the best way to go about doing this?

I am trying to do something like this



but the code I have doesn't seem to do what I want...

Code: [Select]
