admin panel help - editing data

**llorax** · 04-03-2007, 09:02 PM

I'm still new to this whole PHP thing and Ive essentially created a form where if you type in the date listed in the database, it will display the events information and give you the option to edit.

Below is the code that I have constructed for the page that displays the information based on examples and tutorials.

I get an error message on the 18th line which talks about "$current_???_html .= "$current_???_html" I just put the ?? there because I figured this code is needed but Im not sure what it means or what it is suppose to be coded as. Can anyone explain this and help me get my code working. Thanks in advance!

PHP Code:


<?php
    
    include 'session.inc.php';
    include 'config.inc.php';
    include 'db.inc.php';
    
    $link = db_connect();

    if ($_POST != '')
        $id = $_POST['hid'];
    else
        $id = $_GET['id'];

    $query = "SELECT ('$date','$venue','$location','$information') FROM showdates;
    $result = db_query($query, $link);

    if (mysql_num_rows($result)) {
        $current_horses_html = "<table cellpadding=1 cellspacing=2 width=99&#37; border=0><tr align='center' bgcolor='#cccccc'><td><B>Date</B></td><td><B>Venue</B></td><td><B>Location</B></td><td><B>Information/B></td><td colspan='2'><B>Action</B></td></tr>";
        while (list($id, $date, $venue, $location, $information) = mysql_fetch_array($result)) {
            $current_showdates_html .= "<tr bgcolor=#FFFFFF align=center><td>$date</td><td>$venue</td><td>$location</td><td>$information</td><td><a href='edit.php?id=$id'>Edit</a></td></tr>";
        }
        $current_???_html .= "<tr><td></td><td></td></tr></table>";
    } else {
        $current_???_html = '<p>Show does not exist. Please try again.</p>';
    }
    
    if (isset($_GET['err_msg'])) {
        $err_msg = $_GET['err_msg'];
        if (!empty($err_msg)) {
            echo "<p><b>Error</b>:<br>$err_msg</p>";
        }
    }

Well, I see a couple of things that is wrong with the code (and anyone of these could cause the error message.

Code:

<?php
    
    include 'session.inc.php';
    include 'config.inc.php';
    include 'db.inc.php';
    
    $link = db_connect();

    if ($_POST != '')
        $id = $_POST['hid'];
    else
        $id = $_GET['id'];

    $query = "SELECT ('date','venue','location','information') FROM showdates";
    $result = db_query($query, $link);

    if (mysql_num_rows($result)) {
        $current_horses_html = "<table cellpadding=1 cellspacing=2 width=99 border=0><tr align='center' bgcolor='#cccccc'><td><B>Date</B></td><td><B>Venue</B></td><td><B>Location</B></td><td><B>Information/B></td><td colspan='2'><B>Action</B></td></tr>";
        while (list($id, $date, $venue, $location, $information) = mysql_fetch_array($result)) {
            $current_horses_html .= "<tr bgcolor=#FFFFFF align=center><td>$date</td><td>$venue</td><td>$location</td><td>$information</td><td><a href='edit.php?id=$id'>Edit</a></td></tr>";
        }
        $current_horses_html .= "<tr><td></td><td></td></tr></table>";
    } else {
        $current_horses_html = '<p>Show does not exist. Please try again.</p>';
    }
    
    if (isset($_GET['err_msg'])) {
        $err_msg = $_GET['err_msg'];
        if (!empty($err_msg)) {
            echo "<p><b>Error</b>:<br>$err_msg</p>";
        }
    }

Anyways, that is your code that has been editted, and it should work (according to the syntax).

Hope this helps.

**llorax** · 04-04-2007, 02:16 AM

but why should it say horses? What is that referring to?

**thetestingsite** · 04-04-2007, 02:19 AM

This variable:

Code:

$current_horses_html

could be whatever you want it to be (as long as you keep it the same throughout your script). In other words, you could name it anything and it will still work (as long as you replace all occurrences of the old variable in the script).

Hope this helps.

**llorax** · 04-04-2007, 02:51 AM

now im getting this error:

Could not send query: Operand should contain 1 column(s)

**thetestingsite** · 04-04-2007, 02:57 AM

Sorry, completely overlooked this part:

Code:

$query = "SELECT ('$date','$venue','$location','$information') FROM showdates";

Remove the parts in red (I also editted the code I editted for you originally).
Hope this helps

I believe I edited everything you suggested and I'm still getting the same error message.

PHP Code:


<?php

    

    include 'session.inc.php';

    include 'config.inc.php';

    include 'db.inc.php';

    

    $link = db_connect();



    if ($_POST != '')

        $id = $_POST['hid'];

    else

        $id = $_GET['id'];



    $query = "SELECT ('date','venue','location','information') FROM showdates";

    $result = db_query($query, $link);



    if (mysql_num_rows($result)) {

        $current_shows_html = "<table cellpadding=1 cellspacing=2 width=99 border=0><tr align='center' bgcolor='#cccccc'><td><B>Date</B></td><td><B>Venue</B></td><td><B>Location</B></td><td><B>Information/B></td><td colspan='2'><B>Action</B></td></tr>";

        while (list($id, $date, $venue, $location, $information) = mysql_fetch_array($result)) {

            $current_shows_html .= "<tr bgcolor=#FFFFFF align=center><td>$date</td><td>$venue</td><td>$location</td><td>$information</td><td><a href='edit.php?id=$id'>Edit</a></td></tr>";

        }

        $current_shows_html .= "<tr><td></td><td></td></tr></table>";

    } else {

        $current_shows_html = '<p>Show does not exist. Please try again.</p>';

    }

    

    if (isset($_GET['err_msg'])) {

        $err_msg = $_GET['err_msg'];

        if (!empty($err_msg)) {

            echo "<p><b>Error</b>:<br>$err_msg</p>";

        }

    }

Question, do you have a function in any of these files:

session.inc.php,
config.inc.php,
db.inc.php

that has a function named "db_query()"?

If not, then you may want to try changing this line:

Code:

$result = db_query($query, $link);

to this:

Code:

$result = mysql_query($query, $link);

Hope this helps.

**llorax** · 04-04-2007, 08:38 PM

my db inc file does include that function:

PHP Code:


<?php



function db_connect() {

    global $cfg;

    $link = mysql_connect($cfg['db_server'], $cfg['db_user'], $cfg['db_pass']) or die("Could not connect: " . mysql_error());

    mysql_select_db($cfg['db_name']) or die("Could not select database: " . mysql_error());

    return $link;

}



function db_query($query, $link) {

    $result = mysql_query($query, $link) or die("Could not send query: " . mysql_error());

    return $result;

}



function db_close($result, $link) {

    /* Free resultset */

    if (isset($result)) {

        mysql_free_result($result);

    }



    /* Closing connection */

    mysql_close($link);

}

?>

Ok, I'm going to try this once again.

Code:

<?php
    
    include 'session.inc.php';
    include 'config.inc.php';
    include 'db.inc.php';
    
    $link = db_connect();

    if ($_POST != '')
        $id = $_POST['hid'];
    else
        $id = $_GET['id'];

    $query = "SELECT (`date`,`venue`,`location`,`information`) FROM showdates";
    $result = db_query($query, $link);

    if (mysql_num_rows($result)) {
        $current_shows_html = "<table cellpadding=1 cellspacing=2 width=99 border=0><tr align='center' bgcolor='#cccccc'><td><B>Date</B></td><td><B>Venue</B></td><td><B>Location</B></td><td><B>Information/B></td><td colspan='2'><B>Action</B></td></tr>";
        while (list($id, $date, $venue, $location, $information) = mysql_fetch_array($result)) {
            $current_shows_html .= "<tr bgcolor=#FFFFFF align=center><td>$date</td><td>$venue</td><td>$location</td><td>$information</td><td><a href='edit.php?id=$id'>Edit</a></td></tr>";
        }
        $current_shows_html .= "<tr><td></td><td></td></tr></table>";
    } else {
        $current_shows_html = '<p>Show does not exist. Please try again.</p>';
    }
    
    if (isset($_GET['err_msg'])) {
        $err_msg = $_GET['err_msg'];
        if (!empty($err_msg)) {
            echo "<p><b>Error</b>:<br>$err_msg</p>";
        }
    }

?>
<html>

Notice the parts in red in the query. This should do it. Hope this helps.
