I have a "Change E-mail Address" script that has 4 queries in it, and I just realized that I don't create a DB Connection until Query #2 in my script, yet things work fine?!

The link is like this, www.mysite.com/signup?ref=johnsmith. The cookie doesn't show if I go to that url page. But it does show up once I reload the page. So I'm wondering if it's possible to show the cookie the first time around, instead of reloading the page? Here is my code.
// This is in the header
$url_ref_name = (!empty($_GET['ref']) ? $_GET['ref'] : null);
if(!empty($url_ref_name)) {

$date_of_expiry = time() + 60 * 60 * 24 * $number_of_days;
setcookie( "ref", $url_ref_name, $date_of_expiry,"/");
} else if(empty($url_ref_name)) {
if(isset($_COOKIE['ref'])) {
$user_cookie = $_COOKIE['ref'];
}
} else {}
// This is for the sign up form
if(isset($_COOKIE['ref'])) {
$user_cookie = $_COOKIE['ref'];
?>

I am displaying rows from a database onto a page using: while($row=mysql_fetch_array($query)){ echo $row['name']; } I need to figure out how to limit the rows shown to the page to 100. And if there are 100 rows on the page, a link will be displayed at the bottom, that says "Next 100". Then this will display the next 100 rows. Can you give an example how to do this please? Thanks Hi , I know my code sucks but i'm learning fast!! I'm trying to show a form if the qty value in a database == 10 or a different form if the value ==20. I tried but failed.

I may also include up to 20 images to check if they exist. Better way to do this? Hi,
sorry if there already is a topic regarding my question.. I probably didn't find the right words to describe it properly.. would appreciate a link if anybody knows
I'm making a search form for an archive and my problem is that the labeling says e.g. "1400-3500 A-C".. Now i don't want to make thousands of entrys for 1 file.. How do i find that one file while searching for a number in between, like "1420" or "B"?
Thanks in advance!

Edited by localhobo, 13 October 2014 - 01:28 PM. I have a web site where users can gain points, when they use my site. For example, if the user spends $10.00 then the user will get 10 points. In my web site there is a list of 10 retails (name). When the user clicks the link it will redirect to retailers website, where user can buy items. How can I find out how much the user has spent on the retailer? Thank you. how can i find reference to something like this "navigationID=3" or "navigationID=44" within a string and then re write it to become something like this "/en/content/3/Link_Name"? there could be more than one reference within the string and the integer val (ie 3 and or 44) will not be known. Any help with this would be greatly appreciated. I am trying to create a query that selects results from a table called matches. The results from this table must be based on whether or not there are results from another table called match_results. The results from the match_results table must be based on whether or not the row has either a home_id equal to the current team id, or a visitor_id equal to the current team id. If the current team id is equal to the home_id of the result from the match_results table, then the home_score must be greater than the visitor_score. If the current team id is equal to the visitor_id of the result from the match_results table, then the visitor_score must be greater than the home_score. In short, I am trying to make a query that finds a team's match record(wins and losses). If the result from the matches table doesn't have any results from the match_results table with the same match id, then it hasn't been played it. I hope this makes sense. Is there any way to do this in one single query? [attachment deleted by admin] like I said I'm not very good in coding. so your help to solve this one is more than appreciate. this is what I want to do.... IF I have an image_id1 in the database please show it. other than that please show me the TBC.jpg picture. in php/sql how this will be write. thanks sebastien I'm trying to right this code Code: [Select] <option <?php echo $pageName == 'Home' ? 'selected="selected"' : ''; ?>>Home</option> In PHP Here is my attempt I know it's wrong but I can't get it to work. echo "<option> {$row["menuName"]} " == " {$row["menuName"]} " ? " 'selected=\"selected\"'" : " '' > {$row["menuName"]}</option>"; Instead of the == 'home' i want to echo the menuName and the same goes for at the end of the > In the html, in the source code this is all I get Code: [Select] <select name="menuName" value="options"> '' </option> '' </option> </select> Thanks for any help. Hi, I have a form on my homepage which on submit sends the data to my email. I need to know if it it possible to include in the form a read only field containing the refererid in the URL (for instance, if someone were to have visited my homepage by entering; http://www.mypage.com/?refererid=7777, could I capture that 7777 in one of the form fields so that when the form is submitted I recieve the refererid?) Thanks, any help appreciated... Hi all, I have fwrite() writing to a text file called 'numbers.txt'. The text file content is "23". I learn't fwrite() from the manual, so did: f$fp = fopen('/opt/numbers.txt', 'w'); fwrite($fp, '1'); fclose ($fp); I have used fwrite() to try and make the file content "123", but fwrite() writes over the content of the file, resulting in it just containing "1". I couldn't find anywhere about writing into, rather over, and hoping someone could please help me out. |
