PHP - Want To Know Whats Going On Here?
Hi again,
Here is the code $string .= (substr($string,-1) == '-') ? '' : '-'; I know what this code does but to increase my knowledge could some one tell me what is the question mark symbol for ( ? ) and what is the colon doing. As I have seen the ? in a lot of scripts but have no clue what it does and what its used for cheers! Similar TutorialsHi Friends,
I wanted to know what is new in PHP version 5.6.0. How is it different from its previous versions? How will benefit the security of PHP websites?
Thanks in advance.
So im using textwrangler and usually when you click on the '{' or '}' it will highlight everything inbetween them, well on the top one on line 7 it does not, and i tried messing around with it to try to get it to work cause i keep getting an error on line 8 that says "Parse error: syntax error, unexpected '{' in /home/truckste/public_html/create_topic_parse.php on line 8" Code: [Select] <?php if($username){ header("Location: index.php"); exit(); } if(isset($_POST['topic_submit'])){ if (($_POST['topic_title'] == "" && ($_POST['topic_content'] == "")){ echo "You Did Not Fill In Both Fields.

Im bit stumped here not even sure what to call the prob is it sql query error or php array problem thanks for any help Ive created a process which automatically creates a form for all of the "courses" that are listed in a database. This table shows the name, the course code, the current program the course is under and an option to delete the course. I have created a drop down menu for the user to select any of the current programs to switch the course into. My problem is I have X amount of select fields and radio buttons and I dont know how to tell which one has been changed below is my code, appreciate the help!: case "ep": if (isset ($_GET['id'])){ $id = $_GET['id']; echo "Below lists all of the current courses under this program. Once you have made all of the changes click the submit button at the bottom of the page. <br><br><br>"; $query = "SELECT * FROM courses WHERE cid = $id"; $result = mysql_query($query) or die (mysql_error()); echo "<form action=\"course_process.php\" method=\"post\">"; echo "<table><tr><td><strong>Course Name</strong></td><td><strong>Course Code</strong></td><td><strong>Change Course Program</strong></td><td><strong>Delete</strong></td></tr>"; $i = 0; while ($row = mysql_fetch_assoc($result)){ $r = $row['id']; $query2 = "SELECT * from catagories"; $result2 = mysql_query($query2) or die (mysql_error()); echo "<tr><td> ". $row['name'].

I have 3 of 4 variables outputting correctly but without my id being pulled from the URL NOTHING will get written to my database.

Hi all, Yeah just a fresh pair of eyes needed. It just wont insert into the table and the alert returns a blank. Only thing I can think is thats its posting variables from two different queries...but that shouldnt make a difference...
