PHP - Php Login Out Every Half An Hour Help!

Unfortunately I do not know how to go about doing this in php any simple examples of time and date will be great.


So what I am trying to do is, display to minutes until the next half hour as well as the seconds until the next minute.  Eg.
Code: [Select]
<?php echo $minutes; ?>:<?php echo $seconds; ?>

Any help using the time and or date functions in this case will be great.

Thank you for your stupendous help.

Hi all, Having an issue with some of my php code. The goal is to have two drop-down menus, one that pulls from "ahevents_scenarios". The second pulls the "sides" involved, however it does not go into dropdown. The other issue is that even though there are only 3 sides specified, all 5 show up on the webpage. This is in Joomla.     Here is my code...I think I've looked over this way too much and just can't find my errors anymore.

<?php



if (! $my->id) {

  // shouldn't even get here since menu is viewable only through logged in status

print "<b>Sorry, you must be registered and logged into this site to continue</b>\n";

}

else {



// include standard functions and db info

require_once($_SERVER['DOCUMENT_ROOT'] . "/inc/admin_functions.php");

require_once($_SERVER['DOCUMENT_ROOT'] . "/inc/db_admin_functions.php");



// which scenario we doing?  -- replace with table lookup in future



opendb('ahevents_scenarios');



if(!isset($_POST['action'])) { // display form

    $sqlstr2 = "select id, name from scenarios order by name";

    $result2 = mysql_query($sqlstr2) or die("Error: ".mysql_error()."<br>Query: $sqlstr2");

  // display form

?>



<form name="edit_reg" method="post" action="<? echo $_SERVER[ 'REQUEST_URI' ]; ?>"

<table>

<tr>

<td>Select Scenario: </td>

<td>

<select name="id">

<? while ( $row = mysql_fetch_array($result2)) {

    printf("<option value=\"%s\">%s</option>\n",$row['id'], $row['name']);

}

?>

</td></tr>

<tr>

<td>Which Side?</td>

<td><select name="side">

<option value="side_1">side_1</option>

<option value="side_2" >side_2</option>

<option value="side_3" >side_3</option>

<option value="all" selected>All</option>

</select>

</td></tr>

</table>

<p>

<input type="submit" name="action" value="Get Registrants">&nbsp;

<input type="reset" value="Reset">&nbsp;

<input type="button" name="" value="Back" onClick="history.back()">

</form>

The goal is to download the registrants into a .csv file, which it does, however due to not being able to select a "side", the .csv is blank with only headers, no content.   Thanks for your time Rob

Hi guys,

So here is the deal.

We have a list of brands that excists in a database. There are also images associated with the names. But not all the brands have images. So in the script i read if the file excists.

Well this all works fine but it looks horrible. So i want to break the list in half (or limit it to 24). But i cant limit the sql query.

Is there a way to "limit" a while loop and let it resume on the same page, just to change the layout (multiple collumns)? (I hope i am clear on this... i confuse even myself)



$host = 'localhost';
$user = 'qwerty';
$pass = 'qwerty';
$db = 'qwerty';

$query = "SELECT * FROM ros_brands";

$result = mysql_query($query) or die(mysql_error());

$filename = "/resources/images/mm_files/" . $row['image_file_id'] . ".gif";

while($row = mysql_fetch_array($result)){

$filename = "/var/www/vhosts/test.nl/httpdocs/resources/images/mm_files/" . $row['image_file_id'] . ".gif";

if (file_exists($filename)) {
        echo    "<a href='#'><img src='/resources/images/mm_files/" . $row['image_file_id'] . ".gif' /><span>". $row['name'] ."</span></a>";

} else {
//    echo "The file $filename does not exist";
}

}

I am just helping out a friend with his online store that he would like to add multiple currencies to. I made this script to help him out:
$price = 99.95;
$default_currency = 20;
// displays all the file nodes
if(!$xml=simplexml_load_file('http://www.ecb.int/stats/eurofxref/eurofxref-daily.xml')){
    trigger_error('Error reading XML file',E_USER_ERROR);
} else { 
$array['currency'][1] = 'EUR';
$array['value'][1] = 1.00;
$i = 2;
foreach ($xml->Cube->Cube->children() as $node) {
$arr = $node->attributes();   // returns an array
$array['currency'][$i] = $arr['currency'];
$array['value'][$i] = $arr['rate'];
$i++;
}
}
if (isset($_POST['currency'])){
$currency = $_POST['currency'];
} else {
$currency = $default_currency;
}
$price = $array['value'][$currency] / $array['value'][$default_currency] * $price;
$price = round($price, 2);
$currency_name = $array['currency'][$currency];
echo '<p>Price is '.$currency_name.$price.'<br />
To change currency, select from dropdown box below.</p>';
echo '<form action="currency.php" method="post"><select name="currency">';
$i = 1;
foreach ($array['currency'] as $value){
echo '<option value="'.$i.'">'.$value.'</option>';
$i++;
}
echo '</select><br /><input type="submit" /></form><br />';

$i = 1;
foreach ($array['currency'] as $value){
echo '<p>'.$value.' = '.$array['value'][$i].'</p>';
$i++;
}

But for some reason it only works some of the time and I can't work out why for the life of me.

If I could get some help in the matter, that would be greatly appreciated.

A link to the above example can be found here.

Regards,

I.
