so i want to check if there is a video on inside my db if there is no video and nothing happens but if there is i want it to echo video Code: [Select] <?php if($video == ""){ }else{ echo "VIDEO"; } ?> Similar TutorialsHello, I have created a little voting script for my site. The insertion code into the MySQL databse when they vote is very simple: $ipaddress = addslashes($_POST['ipaddress']); $theid = addslashes($_POST['theid']); $gamert = addslashes($_POST['gamert']); $serveron = addslashes($_POST['serveron']); $db = mysql_connect("localhost", "username", "password"); mysql_select_db("thedb",$db); mysql_query ("INSERT INTO voting (theid,ipaddress,gamert,serveron2) VALUES ('$theid','$ipaddress','$gamert','$serveron') "); Obviously I only want them to be able to vote once. What is the best way to do a check of the IPs already in the database and check against theirs before submitting? Thanks.

I am not getting how sgould i pass the get variable on the link of the button??? -Pranshu Agrawal pranshu.a.11@gmail.com Hello their, I'm wanting to use PHP to check to see if a username and password match a remote RDP server. The reason I ask is because I want to verify that the information the user is giving is correct. I'm looking though LDAP but I have no idea what I'm looking for. To recap, I would like to login to a RDP server and return a result based on if it completed. Thank-you for reading Paul P.S Sorry for the bad English, I seemed to forgot how to spell some words and have had to replace them with longer sentences I am unable to execute mysql_num_rows properly in this program. Code: [Select] <?php $link=mysql_connect("localhost","root",""); $db = mysql_select_db("myDB",$link); $result = mysql_query("SELECT * FROM jobs WHERE jobType=abc"); $num = mysql_num_rows($result); echo "Found $num records"; ?> error is mysql_num_rows() expects parameter 1 to be resource Hey, I'm trying to check if a username is unique, but for some reason none of the methods that I've looked up seem to work. I'm aiming for the code to check if a username is unique, and if get the user to input the name again. $get = "SELECT `i` FROM `m` WHERE `i`=\"$r\""; $checkResults = mysql_query($getRandomness); while(mysql_num_row($checkResults) > 0) { //some code... //check again $get = "SELECT `i` FROM `m` WHERE `i`=$r"; $checkResults = mysql_query($get); } The error comes from the while line, but it comes up during the first check because the record is empty. This is the error: "Fatal error: Call to undefined function mysql_num_row()" This is suppose to check a table to see if it has a value in it. I get this error: Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /homepages/6/d365637117/htdocs/EE Live/Active/Inc/session.php on line 33 This is the code if($checkProfile) { $result = mysql_query("SELECT prof_pic FROM members_profile WHERE id = '".$_SESSION['EEID']."'"); $mem_num_rows = mysql_num_rows($result); if($mem_num_rows =1) { } What is the best way to check for a Date in a Form? I see there is a CheckDate() function, but how does that know what format the Date is in? Should I use a Regular Expression? My Form Field is just a Text Box... Thanks, Debbie Gud pm!! So i made this script to check if a username and password exist but it kinda fails me. It gives me a database connection error from my confirm_query() which means it returned false? so here's my code: Code: [Select] function check_if_exist($username, $password) { global $connection; $query = "SELECT username, hashed_password"; $query .= "FROM users "; $query .= "WHERE username = '$username' "; $query .= "AND hashed_password = '$password' "; $query .= " LIMIT 1"; $result_set = mysql_query($query, $connection); confirm_query($result_set); if(mysql_num_rows($result_set) == 1) { return true; } else { return false; } } my confirm_query(): Code: [Select] function confirm_query($result) { if(!$result) { die("Database connection failure ". mysql_error()); } } I have a another script to check if the email exist and it works perfectly, i dunno why this won't work properly.. maybe another simple mistake..
