[code=php] if($variable) { //statements } [/code] This simply means, [i] if(true) [/i]. If a variable is set and if doesn't have values 0,false,'', it will execute corresponding statements. Example, [code=php] <?php $a = NULL; if($a) { echo "$a is true<br />"; } else { echo "$a is false<br />"; } …

Without relevant code, it is next to impossible to know what is going wrong.

[QUOTE=kadimi;827098]As a beginner, I suggest you use the function "require" like this: [code=php](require "includes/common.php");[/code] Yes, require has a different syntax, to avoid future problems, always surround the hole statement with parenthesis.[/QUOTE] What future problems are you talking about ? Could you explain this a bit better ?

I haven't used tomcat, but for apache, its [url]http://localhost[/url] to access the root directory. You can find the config file httpd.conf in conf directory.

What is the error ? I am still confused about what you want and what is the problem. Do you mean something like this ? [code=php] <?php if(isset($_POST['submit'])) { $total = $_POST['field1']+$_POST['field2']+$_POST['field3']+$_POST['field4']; if($total % 4 == 0) { echo "$total Divisible by 4.."; } else { echo "$total Not divisible …

Try[icode] or die(mysql_error()); [/icode] instead of your custom message. This will let you know what exactly is the error.

[code=php] <?php $reg = '/<h2>(.*)<\/h2>/s'; $fulltext="<h1>Welcome</h1> <h2>Welcome to this website</h2> <p>Some text here. </p>"; preg_match($reg,$fulltext,$matches); print $matches[1]; ?> [/code] This will do.

[QUOTE=stevehart808;826118]Maybe it got to do with [code] $date = $date15_year.'-'.$date15_month.' '.$date15_date; [/code][/QUOTE] No. That is just fine. Use print_r($_POST); to see what is getting posted and what is not.

The simplest way to validate username and password is to query the table with both username and password and see how many rows it returns. For example, [code=php] $query = "select * from table where username='$username' and password='$password'"; $result = mysql_query($query); if(mysql_num_rows($result) == 1) { //echo valid user } else …

Most of the time (like 99% of the time), people tend to forget how important it is to sanitize the user's input. Using mysql_real_escape_string will prevent sql injections by escaping [b]'[/b] and [b]/[/b].

The simplest answer to your question is, No. Its not possible to disable 'back' button of the browser. As far your question is concerned, When the user logs in, you can set a session variable, say,[icode] $_SESSION['validuser'] = true; [/icode] And on every page, check if $_SESSION['validuser'] is true.

Without submitting the page, You can't get the selected option's value in php. However, in Javascript, you can access it.

Use [icode] error_reporting(E_ALL ^ E_NOTICE); [/icode] on top of your script (after session_start).

[quote]the submenu just stays out...[/quote] I tried your code and it works perfectly !

Instead of having separate names for checkbox, use checkbox array and assign different values to it. When you click on the submit button, only those checkboxes which were checked would be posted.

Instead of creating a comma separated string, why don't you use foreach loop ? You can get the key as well as the value. Use the 'key' as variable name!

The way you are doing it is wrong. Try this.

Here are my 2 cents. You can disable those notices by using [icode]error_reporting(E_ALL ^ E_NOTICE);[/icode] on top of your script. If you don't want to disable it but still want to fix the notices, initialize a variable to 0 (or null if its a string). ie., $i = 0; $string …

Edit your post. Use [code] tags to wrap your code for better readability (and better response).

In the script (the url), check if the user is a unique user (by checking his IP address). If he is a unique user, update count. :-/ You can't call a javascript event (onclick) to update the table. You can try the same with Ajax though. ie., Onclick, call the …

You cannot access $_POST['startdate'] in action2.php . Its only available in action.php since it is posted from form.php to action.php .

If you use die function and if an error occurs and prints the die message, then its pretty obvious where exactly the error has occurred ! For runtime errors, php parser will only let you know where the error has occurred if you have error_reporting turned on.
