Why am I use a die() all tags after ?> (i have in mind HTML tags) don't work? How can I fix it?

I am no expert but more info would probebly not hurt, like example of using it and destribing what is happening.

Your question makes no sense whatsoever, but I will try to explain. die() is an alias function for [man]exit/man. If you look in the manual, you will see that either of these functions halts execution of the script. Basically, this means nothing after it will be parsed when the data is sent to the browser, so you will only see what is there before you call the function.

What exactly are you trying to do here?

I guess snakebit is looking for something like try and catch so that even exception occurs, the script can continue to execute.

I know that the func halt the script, but how i can make it not to halt script after ?>

<table width="400" border="1" cellspacing="0" cellpadding="5">    <tr>      <th colspan="2" scope="row">  	<?php   	die ("some problem");  	?>  	</th>    </tr>    <tr background="images/bgaddict.gif">      <th scope="row">&nbsp;</th>      <td>&nbsp;</td>    </tr>  </table>

The problem is that the code after ?> did not execute.
exm.1
die()

exm.2
echo ""

How can I make it to halt on PHP code?

well the Die command is not breaking your site, it is doing what it needs to do. You probebly want to change the way you are running the code, from where I am sitting the only thing I can think of is telling showing your code so we can look at it, or possibly trying to describe exactly what you are trying to do.

				<?php

	//Nickname&password check

    echo "<span class=\"style1\">";
		if(empty($_POST["nickname"]))
		{
		 echo "Error msg</h5>";
		}
		elseif (strlen($_POST["nickname"]) > 15)
		{
		  echo "<h5>Error msg</h5>";
		}
		elseif(empty($_POST["altnickname"]))
		{
		  echo "<h5>Error msg</h5>";
		}
		elseif(strlen($_POST["altnickname"]) > 15 || strlen($_POST["altnickname"]) == 0)
		{
		  echo "<h5>Error msg</h5>";
		}
		elseif(empty($_POST["password"]) || empty($_POST["cpassword"]))
		    {
		echo "<h5>Error msg</h5>";
		    }
		elseif (strlen($_POST["password"]) < 5 || strlen($_POST["password"]) > 15)
		    {
		echo "<h5>Error</h5>";
		    }
		elseif (!(strlen($_POST["password"]) == strlen($_POST["cpassword"])))
		    {
		 echo "<h5>Error msg</h5>";
		    }
		elseif (!($_POST["password"] === $_POST["cpassword"]))
		    {
		 echo "<h5>Error msg</h5>";
		    }
		else
		    {

			$_POST["password"] = $_POST["password"];
	                $_POST["nickname"] = $_POST["nickname"];
	                $_POST["altnicname"] = $_POST["altnicname"];
        echo "</span>";


	$db_host     = "localhost";
	$db_uname    = "icebreaker";
	$db_password = "123456";


	$connect = mysql_connect($db_host, $db_uname, $db_password)
	or die ("<h5>Error msg</h5> <br>");
	$selectdb = mysql_select_db ('cs');
	$sqlquery = "INSERT INTO
	channelinf (name, nickname, altnickname, birthmonth, birthday, birthyear, class, picture, email, page, password)
	VALUES ('$_POST[name]', '$_POST[nickname]', '$_POST[altnickname]', '$_POST[birthmonth]', '$_POST[birthday]', 
'$_POST[birthyear]', '$_POST[class]', '$_POST[picture]', '$_POST[email]', '$_POST[page]', '$_POST[password]')";
		$queryresult = mysql_query($sqlquery) 
		or die ("<h5>Error msg</h5>");
        echo "<span class=\"style2\">";
        echo "<center>some text</center>";
		echo "<P>&nbsp;</P>";
		echo "<center><meta http-equiv=\"refresh\" content=\"5;url=index.html\"> some text <a href=\"index.html\"><b>ooe</b></a></center>";
        echo "</span>";
        }
		?>

The problem is that all images (or tables and etc.) which follow after the code didn't want to show. Is there way to make the function work only in PHP code, not to touch the HTML code?

First stop using die(). Then the simple answer is just to have it echo() a error message instead of die(). Or a better way would be to use conditionals to decide whehter or not to execute subsequent code blocks, and echo out your error message if the conditional fails. That way you won't stop the parsing of the document which is what die() does, it stops all parsing dead in it's tracks.

A pseudocode example of what I'm suggesting:

if(dbconnects) {

  if(!do insert) echo errormsg

} else echo errormsg

now put the rest of your echos

Also I would suggest not echoing out the rest of the HTML as it appears to be fixed text, just put in a closing php tag and put the HTML after it without the echos and the enclosing quotes (also don't forget to remove the '\'s if you do this.

snakebit

I rerwrite the code.

		$connect = dbx_connect(DBX_MYSQL, $db_host,$db_name,$db_uname, $db_password);          if (!$connect)          {          echo " error_msg";          }else{          $sqlquery = "INSERT INTO  			channelinf (name, nickname, altnickname, birthmonth, birthday, birthyear, class, picture, email, page, password)  			VALUES ('$_POST[name]', '$_POST[nickname]', '$_POST[altnickname]', '$_POST[birthmonth]', '$_POST[birthday]', '$_POST[birthyear]', '$_POST[class]', '$_POST[picture]', '$_POST[email]', '$_POST[page]', '$_POST[password]')";  			$queryresult = mysql_query($sqlquery);  	        echo "<span class=\"style2\">";  	        echo "<center>Aaoaoa eioi?iaoey aaoa onaoii auaaaaia a aacaoa aaiie!</center>";  			echo "<P>&nbsp;</P>";  			echo "<center><meta http-equiv=\"refresh\" content=\"5;url=test.html\"> Aei neaa 5 naeoiae naeouo ia na ca?aae aaoiiaoe?ii, eeeeiaoa <a href=\"test.html\"><b>ooe</b></a></center>";          echo "</span>";          }  	}

Now it work perfect 🙂 🙂 🙂
Thanks for the help, you rulllll 🙂
