PHP - Check Sql Database For Value, If Statement

Hi everyone,

I am currently making a page for a friend to upload a bunch of photos at a time.

I was quite pleased that after a bit of googling and trial and error, I figured out how to do this so that multiple records could be added to my table with one submit button.

However, my form has 10 browse iconcs. A few tests have revealed that my problem is that if only one picture is uploaded, I still get 9 entries in my database, which I don't want.

My question is how can I alter the code so that a row is only populated in the database if an image is uploaded.

I guess something that sort of says :

   if($imgx!="")   
{
populate that row in the table
}

else

{
don't
}


...and the same for $imgx002 through to $imgx010


The current query is below. Any pointers are much appreciated.

Code: [Select]


$query = "INSERT INTO photo_uploads (date, photo_name)" . "VALUES (NOW(), '$imgx'), (NOW(), '$imgx002'), (NOW(), '$imgx003'), (NOW(), '$imgx004'), (NOW(), '$imgx005'), (NOW(), '$imgx006'), (NOW(), '$imgx007'), (NOW(), '$imgx008'), (NOW(), '$imgx009'), (NOW(), '$imgx010')";

Hello I am creating a simple Discussion Forum, and I cant get past my IF Statement to verify topics exist? Please help?

<?php

//check for required info from the query string
   if (!$_GET[topic_id]) {
      header("Location: topiclist.php");
         exit;
}

//connect to server and select database
   $link = mysql_connect('votpservicescom.ipagemysql.com', 'mantest', 'testman')
    or die(mysql_error());
   mysql_select_db("learn2db",$link) or die(mysql_error());   

I have database that is a list of categories that I would like to insert into a switch statement.
This is the only way that I know how to do it right off hand and of course it doesn't work.
I've looked on the internet and found examples but they are slightly over my head as ways to do it.

Depending on $group which comes from the url a title an h1 would be assigned.

Code: [Select]
$q = "SELECT * FROM categories";
$r = @mysqli_query ($dbc, $q);
switch ($group)
{
if ($r) { //If $r ran OK
while ($row = mysqli_fetch_array($r, MYSQLI_ASSOC)){
case '$row['id_cat']': $h1 = '.$row['group']';
break;
}
}
}
Thanks
S

just a little confused where ( brackets go in this statement . im just wanting to to display the information differently depending on which message is returned from the database.

thanks
Code: [Select]

if ($info['message'])="<a href=\"freindacept.php?username=$myusername\">Has sent you a friend request </a>";{

Echo "<a href='viewprofile.php?username={$info['username']}'><img src='http://datenight.netne.net/images/".$info['img'] ."' width='30' height='30''></a>".$info['from_user']." ".$info['message'];
}elseif  ($info['message'])="You have sent a contact request to";

Echo " .$info['message']<a href='viewprofile.php?username={$info['username']}'><img src='http://datenight.netne.net/images/".$info['img'] ."' width='30' height='30''></a>".$info['from_user'].";
}

Hi guys,

I need your help. I am checking on a database as I want to see if I have the same value in the url and in the database.


Code: [Select]
<?php
session_start();
    define('DB_HOST', 'localhost');
    define('DB_USER', 'mydbuser');
    define('DB_PASSWORD', 'mydbpass');
    define('DB_DATABASE', 'mydbtable');
       
    $errmsg_arr = array();
    $errflag = false;

    $link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
    if(!$link) {
  die('Failed to connect to server: ' . mysql_error());
    }

    $db = mysql_select_db(DB_DATABASE);
    if(!$db) {
  die("Unable to select database");
    }

   function clean($var){

return mysql_real_escape_string(strip_tags($var));
    }
  
    $username = clean($_GET['user']);
    $password = clean($_GET['pass']);
    $test = clean($_GET['test']);
    $public = clean($_GET['public']);
   
   
   if (isset($_GET['user']) && (isset($_GET['pass']))) {
    if($username == '' || $password == '') {
  $errmsg_arr[] = 'username or password are missing';
  $errflag = true;
    }
} elseif (isset($_GET['user']) || (isset($_GET['test'])) || (isset($_GET['public']))) {
    if($username == '' || $test == '' || $public == '') {
  $errmsg_arr[] = 'user or others are missing';
  $errflag = true;
    }
  }

    if($errflag) {
  $_SESSION['ERRMSG_ARR'] = $errmsg_arr;
  echo implode('<br />',$errmsg_arr);
   }
   else {
  $qry="SELECT * FROM members WHERE username='$username' AND passwd='$password'";
  $result=mysql_query($qry) or die('Error:<br />' . $qry . '<br />' . mysql_error());


if ($username && $password) {
  if(mysql_num_rows($result) > 0) {
     $qrytable1="SELECT images, id, test, links, Public FROM user_list WHERE username='$username'";
    $result1=mysql_query($qrytable1) or die('Error:<br />' . $qry . '<br />' . mysql_error());

    while ($row = mysql_fetch_array($result1)) {
        echo "<p id='test'>";
        echo $row['test'] . "</p>";
        echo '<p id="images"> <a href="images.php?test=test&id='.$row['id'].'">Images</a></td> | <a href="http://' .  $row["links"] . '">Link</a> </td> | <a href="delete.php?test=test&id='.$row['id'].'">Delete</a> </td> | <span id="test">'.$row['Public'].'</td>';
     }
   } else {
    echo "user not found";
  }
} elseif($username && $test && $public) {
    $qry="SELECT * FROM members WHERE username='$username'";
    $result1=mysql_query($qry) or die('Error:<br />' . $qry . '<br />' . mysql_error());
    
    if(mysql_num_rows($result1) > 0) {     
      $qrytable1="SELECT Public FROM user_list WHERE username='$username' && test='$test'";
      $result2=mysql_query($qrytable1) or die('Error:<br />' . $qry . '<br />' . mysql_error());
      
      if(mysql_num_rows($result2) > 0) {
        $row = mysql_fetch_row($result2);
        mysql_query("UPDATE user_list SET Public=('$_GET[public]') WHERE username='$username' AND test='$test'");
        echo "update!";
      } else {
        echo "already updated!";
      }
    } else {
      echo "user not found";
    }
  }
} 
?>
This is the function I use to check the value in the database:

Code: [Select]
if (mysql_affected_rows($result2) > 0) {
         mysql_query("UPDATE user_list SET Public=('$_GET[public]') WHERE username='$username' AND test='$test'");
         echo "you have update it!";
       } else if (mysql_affected_rows($result2) < 0) {
         echo "it is not on the database";
       } else {
         echo "you have already updated!";
       }

When i input the different value in a url bar while the records are not the same as the value in the url and in the database, i can't get passed and I am keep getting "you have already updated!!" when the value in a database are different than I have input in a url.

Do you know how i can get pass it when I have input the different value in the url while it is not the same in the database?

Any advice would be much appreicated.

Thanks,
Mark

How do you check if a MySQL or MySQLi server is available through php.
I'm trying to make a short script that makes sure the users server can run the application. Like all the popular ones do

Hello
i have a text box and a button on my webpage and want to get the text box to find the username i type into it from the database and when it does it will then go to number and delete any text that is under usernames number field as you can see i have no idea how.

Code: [Select]
$result = mysql_query("DELETE FROM mytable WHERE username='$username1' AND number='$number1'" );
Code: [Select]
<form name="form1" method="post" action="p.php">
<p><input type="submit" value="Enter" /></p>
<input name="username" type="text" id="username" size="15" maxlength="35" value="<?php echo $username1; ?>" />
</form>

I'm creating a game where 2 people, on separate computers can battle each other. I'm doing it turn-based, like Final Fantasy but I came across a problem, how do I check if the other person has ended their turn?

I was thinking that I would have an area in my database that would be true/false if it was their turn. So if the first person ends their turn, their 'turn' becomes false in the database, but how, on the other users computer, do I constantly check if the 'turn' has become false so that they may now play without having to keep updating the browser.

Or is their a better way to do something like this?

Hello. I want to check if an e-mail address is stored into a database. I've found this type of code:

Code: [Select]
function verifmail($email)
{
    db_connect();
    if (mysql_num_rows(mysql_query("SELECT email FROM users WHERE email='$email';")))
    {
        return 1;
    }
    else
    {
        return 0;
    }
}
Is it correct ? Is there any other way?

I am building a system where people are able to choose a food menu, they can modify each dish if needed and then say how many of each item they need for the order.

So when they pick the breakfast menu, it selects all starters, mains and desserts.  Should something need to be edited (sausages changed to vegitarian sausages) the user should be able to overtype what has been populated from the select statement)

When the form is submitted, the order needs to be linked to the current job which is in a field ssm_job.job_id but the changes to the menu items need to be stored somewhere for the current order only.  This obviously needs to be accessile later so further changes can be made if needed.  I am not sure of the best way to go about this as i am trying not to save every item in another database (just trying to be tidy)

Any advise on this would be greatly appreciated.

I have had help on this project in relation to an sql and the background can be found below, the help has been amazing but as this is a very different question i thought i would start a new thread.

 

Kind Regards

I have a set of 26 checkboxes that are stored in an array. The below code dumps the comma separated array values into a single record column.


Code: [Select]
// dumping the type of job checkboxes

$type = $_POST['type'];
  var_dump($type);
 
    // Setting up a blank variable to be used in the coming loop.
  $allStyles = "";
 
  // For every checkbox value sent to the form.
  foreach ($type as $style) {
    // Append the string with the current array element, and then add a comma and a space at the end.
    $allTypes .= $style . ", ";
  }
 
    // Delete the last two characters from the string.
  $allTypes = substr($allTypes, 0, -2);


// end dumping the type of job checkboxes


This works great! But my needs go past this. The record can be edited. So I need to get the values back out of the database and populate the correct check boxes for editing.

The checkboxes are generated by this code.


Code: [Select]
<div class="text">Job Type&nbsp;(<a class="editlist" href="javascript:editlist('listedit.php?edit=typelist',700,400);">edit list</a>):</div>
<div class="field">

<?PHP

$connection=mysql_connect ("localhost", "name", "pass") or die ("I cannot connect to the database.");
$db=mysql_select_db ("database", $connection) or die (mysql_error());
$query = "SELECT type FROM typelist ORDER BY type ASC";
$sql_result = mysql_query($query, $connection) or die (mysql_error());
$i=1;
echo '<table valign="top"><tr><td>';
while ($row = mysql_fetch_array($sql_result)) {
$type = $row["type"];
    if ($i > 1 && $i % 26 == 0)
      echo '</td><td>';
  else if ($i)
  echo '';
  ++$i;
  echo "<input style='font-size:10px;' name='type[]' type='checkbox' value='$type'><span style='color:#000;'>$type</span></input><br/>";
}
  echo '</td></tr></table>';

?>
 
</div>


I am having a problem getting these checkboxes repopulated. I think that a way to do this is to:

Get the values out of the database in a array
Compare the values the list of all possible values.
Check the boxes of the values confirmed to be there.

I didn't build the application so I need help to work through this problem.

I'm trying to get a nickname system working for a little project, but I've run into a problem.

This code that I wrote here gets the users nickname from their username:

Code: (php) [Select]
$user = $_GET['user'];
@mysql_select_db("db") or die( "Unable to select database");

$query = mysql_query("SELECT `nickname` FROM `info` WHERE `username`='$user'");

       WHILE($rows = mysql_fetch_array($query)):
           $nickname = $rows['nickname'];
           echo $nickname;
        endwhile;
?>

But the problem is, if the user doesn't have a nickname then it just turns up blank. How can I check if the output of $nickname is blank and if it is then just return their normal name ($user)

Thanks

Oh, and how to you format php code to look like php code on these forums?

I embed YouTube videos on my site.   The problem is, the videos often get deleted by the user, which means that the videos obviously become unavailable on my site.   This happens often, which means that I regularly have to look through my site, find unavailable videos and delete them.   I am looking for an automated way of doing this.   Here's what I've got so far:

<?php
    $con = mysql_connect("", "", "");
    mysql_select_db("");
    $qry = "SELECT video_id FROM `table`";
    $run = mysql_query($qry, $con);    
    while($row = mysql_fetch_assoc($run)) {    
        $headers = get_headers("http://gdata.youtube.com/feeds/api/videos/{$row['video_id']}");
        if(!strpos($headers[0], '200')) {
            echo "Unavailable: {$row['video_id']}<br />";
            return false;
        }
        else {
            echo "Available: {$row['video_id']}<br />";
        }
    }
?>

The code's very slow and doesn't work. It produces a list of available videos and then stops when it finds one that is unavailable. The problem is, the video that it says is unavailable is usually available, which means that it's getting it wrong.   Is there a faster, more accurate way of doing it?   Basically, I want a fast and accurate way of checking the availability of the thousands of videos in my database and I want to produce a list of the ones that are unavailable.

Hi all,

I've got a website for an event, each team have their details on a page which are recalled from a SQl database.

But I'm wanting to create a password input box for each team, so when they enter the correct password they are taken to a page containing forms where they can edit the team details.

Here is the page with the users details on where they anter the password: http://www.wharncliffenetwork.co.uk/wrc/entered/team.php?id=8

I'm not sure how to code it, Can an IF statement be used? Anyone got any pointers? I'f been unsuccessful in finding a tutorial or something similar.

Hope that makes sense :S Cheers.
