Also tried change the below code to

if(mysql_num_rows(mysql_query("SELECT userid FROM signup WHERE userid = '$userid'")))

to

if(mysql_num_rows(mysql_query("SELECT * FROM signup WHERE userid = '$userid'")))

but still No go

Muddy_Funster · January 17, 2011

if(mysql_num_rows(mysql_query("SELECT userid FROM signup WHERE userid = '$userid LIMIT 1' ")))  <-------------------(line 32)

is your original code. You have wrapped the LIMIT 1 inside the single quotes, which will result in an error in the sql.

try something like this:

$qry = 'SELECT userid FROM signup WHERE userid = "'.$userid.'" LIMIT 1';
$result = mysql_query($qry) or die ('Error in the SQL SELECT QUERY! : '.mysql_error());
if(mysql_num_rows($result) > 0 ){
//your error code here
}

Hi I was able to insert the data by using the below code:

if(mysql_num_rows(mysql_query("SELECT userid FROM signup WHERE userid = '$userid' ")))

{

$msg=$msg."Userid already exists. Please try another one<BR>";

$status= "NOTOK";

}

There was just a mistake with my database name.

But now when execute i get an error

"Deprecated: Function eregi() is deprecated in C:\wamp\www\signupck.php on line 50

Welcome, You have successfully signed up"

Line (50)------------------------------>(line 50)

if (!eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email))

{

$msg=$msg."enter valid email address<BR>";

$status= "NOTOK";

}

Thanks in Advanced

ereg has been depreciated, it's not supported any more as of PHP 4.

look into this:

Can please let me now the code to validate the email address

Muddy_Funster · January 17, 2011

read through the examples for preg_match()

you will see the similarities to what you are using and should be able to fill in the blanks. I have never used it, so can't really comment on its application. although I am sure there are plenty that have.

Hi,

I have similar problem:

Warning: mysql_num_rows() expects parameter 1 to be

resource, boolean given in

/data/www/www_oobtrebic_cz/mcr11/libraries/joomla/database/database/mysql.php

on line 342

Content of mysql.php:

/**

* Description

*

* @access public

* @return int The number of rows returned from the most recent query.

*/

function getNumRows( $cur=null )

{

return mysql_num_rows( $cur ? $cur : $this->_cursor );

}

/**

* This method loads the first field of the first row returned by the query.

*

* @access public

* @return The value returned in the query or null if the query failed.

*/

function loadResult()

{

if (!($cur = $this->query())) {

return null;

}

$ret = null;

if ($row = mysql_fetch_row( $cur )) {

$ret = $row[0];

}

mysql_free_result( $cur );

return $ret;

}

Row 342 is red.

Can anybody help me?

Thaks a lot§
