Hello, I am making a website for a friend, and he is not very website literate, so I am in the middle of converting all of the content into a CMS based environment so he can edit the content easily.

I have managed to create my database, tables, columns etc and integrate it into the website, now I need to make the housekeeping side of it.

What i need to achieve is a form that can be used to EDIT the current values

here's an example:

edit the columns 'home_header' and 'home_content' in the table 'site_home'

This is my first SQL project and so far I have managed to setup the rest on my own, but I now require your help.

Thanks in advance for ANY help whatsoever.

Curtis
 
Re: Editing SQL Values

PHP: 
<?php
// here somehow connect to sql 

$query = "SELECT * FROM site_home";
$result = mysql_query($query);
$array = mysql_fetch_array($result);

if(isset($_POST['submit']))
{
   $query2 = "UPDATE site_home SET home_header =  $_POST['header']";
   $result2 = mysql_query($query);
}
?>
<form action="" method="POST">
<textarea name="header"><?php $array['home_header']; ?></textarea><?php if($result){ echo "updated"; } ?> 
<input type="submit" name="submit">
</form>
 
Re: Editing SQL Values

Thanks for the quick response. I have hooked it up to my SQL db, but i get this error

Code: 
Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in C:\xampp\htdocs\football\housekeeping\home.php on line 10

edit: this is the code i am currently using:

PHP: 
<?php
include('../config.php');
 
$query = "SELECT * FROM site_home";
$result = mysql_query($query);
$array = mysql_fetch_array($result);
 
if(isset($_POST['header']))
{
   $query2 = "UPDATE site_home SET home_header =  $_POST['header']";
   $result2 = mysql_query($query);
}
?>
<form arction="" method="POST">
<textarea name="header"><?php $array['home_header']; ?></textarea><?php if($result){ echo "updated"; } ?> 
<input type="submit">
</form>
 
Re: Editing SQL Values

expectable, I've written it just from my mind to this quick reply box, without paying much attention..
Anyway,
PHP: 
<?php
include('../config.php');
 
$query = "SELECT * FROM site_home";
$result = mysql_query($query);
$array = mysql_fetch_array($result);
$homeheader = $_POST['header'];

if(isset($_POST['submit']))
{
   $query2 = "UPDATE `site_home` SET `home_header` = '$homeheader'";
   $result2 = mysql_query($query2);
}
?>
<form action="" method="POST">
<textarea name="header"><?php $array['home_header']; ?></textarea><?php if($result2){ echo "updated"; } ?>
<input type="submit">
</form>

Re: Editing SQL Values

It still isnt working. argh.

PHP: 
<?php
include('../config.php');
 
$query = "SELECT * FROM site_home";
$result = mysql_query($query);
$array = mysql_fetch_array($result);
$homeheader = $_POST['home_header'];
if(isset($_POST['header']))
{
   $query2 = "UPDATE site_home SET home_header =  $homeheader";
   $result2 = mysql_query($query);
}
?>
<form arction="" method="POST">
<textarea name="header"><?php $array['home_header']; ?></textarea><?php if($result){ echo "updated"; } ?>
<input type="submit">
</form>

I also had to add a semicolon onto the end of:
PHP: 
$homeheader = $_POST['home_header']

It now comes up with the form but it's not working as it should

screenie:


when i type something and press enter, the changes are not made.



Thank you so much for your help so far by the way
 
Re: Editing SQL Values

Yea, reading my posts directly after I post them = not good(I've edited it like 7x) last edited version should be kinda working though. Anyway I'm off, it's late night alreay, I'm sure you'll figure it out somehow..
 
Re: Editing SQL Values

Not working at all

i type something in the box and submit, but it does not update the database.
 
Re: Editing SQL Values

Well that changed things. I now get this error when i submit the form

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1

Re: Editing SQL Values

I hadn't noticed you'd edited that. Sorry.

Well anyway i have replaced the variables and stuff in later posts, but it still does the same thing as before



no error message whatsoever. I press submit and the form is cleared and no changes are made to the DB

PHP: 
<?php
include('../config.php');
 
$query = "SELECT * FROM site_home";
$result = mysql_query($query) or die(mysql_error());
$array = mysql_fetch_array($result);
$homeheader = $_POST['header'];

if(isset($_POST['submit']))
{
   $query2 = "UPDATE `site_home` SET `home_header` = '$homeheader'";
   $result2 = mysql_query($query2) or die(mysql_error());
}
?>
<form action="" method="POST">
<textarea name="header"><?php $array['home_header']; ?></textarea><?php if($result){ echo "updated"; } ?>
<input type="submit">
</form>

Re: Editing SQL Values

1st notice missing echo in that textarea, so it should be
<textarea name="header"><?php echo $array['home_header']; ?></textarea><?php if($result2){ echo "updated"; } ?>
2nd dunno yet, wait
 
Re: Editing SQL Values

This should definitely work, problem was with that isset()
PHP: 
<?php
mysql_connect(localhost, ales, ******);
mysql_select_db(homopelo);
$query = "SELECT * FROM site_home";
$result = mysql_query($query);
$array = mysql_fetch_array($result) or die(mysql_error());
$homeheader = $_POST['header'];
if(isset($_POST['header']))
{
   $query2 = "UPDATE `site_home` SET `home_header` = '$homeheader'";
   $result2 = mysql_query($query2) or die(mysql_error());
   //to refresh
   header('refresh: 2, testik.php');
}
?>
<form action="" method="POST">
<textarea name="header">
<?php
 echo $array['home_header'];
 ?>
 
</textarea>
<?php if($result2){ echo "updated"; } ?>
<br />
<input type="submit">
</form>

Re: Editing SQL Values

Okay, we are making progress (slowly)

Here's the php code with everything of mine entered correctly:

PHP: 
<?php
mysql_connect(localhost, root, *******);
mysql_select_db(site_home);
$query = "SELECT * FROM site_home";
$result = mysql_query($query);
$array = mysql_fetch_array($result) or die(mysql_error());
$homeheader = $_POST['header'];
if(isset($_POST['header']))
{
   $query2 = "UPDATE `site_home` SET `home_header` = '$homeheader'";
   $result2 = mysql_query($query2) or die(mysql_error());
   //to refresh
   header('location: testik.php');
}
?>
<form action="" method="POST">
<textarea name="header">
<?php
 echo $array['home_header'];
 ?>
 
</textarea>
<?php if($result2){ echo "updated"; } ?>
<br />
<input type="submit">
</form>

the error:

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in C:\xampp\htdocs\football\housekeeping\home.php on line 6
No database selected

Re: Editing SQL Values

mysql_select_db(site_home);
are you sure that it's a dabatase name? Not a column? You could just delete those lines and use your include imo

Also change
header('location: testik.php');
to
header('refresh: 2, home.php');

so
PHP: 
<?php
include('../config.php'); 

$query = "SELECT * FROM site_home";
$result = mysql_query($query);
$array = mysql_fetch_array($result) or die(mysql_error());
$homecontent = $_POST['content'];
$homeheader = $_POST['header'];
if(isset($_POST['content']))
{
   $query2 = "UPDATE `site_home` SET `home_content` = '$homecontent ', `home_header` = '$homeheader'";
   $result2 = mysql_query($query2) or die(mysql_error());
   //to refresh
   header('refresh: 2, home.php');
}
?>
<form action="" method="POST">
<p>header</p>
<input type="text" name ="header" value="<?php  echo $array['home_header']; ?>" />
<br />
<p>content</p>
<textarea name="content">
<?php
 echo $array['home_content'];
 ?>
 
</textarea>
<?php if($result2){ echo "updated"; } ?>
<br />
<input type="submit">
</form>

Re: Editing SQL Values

AHA thanks

i used your revised version above. And yes i did get the database name wrong (shamefully )

It's working!

Thanks so much for your help!
I owe you big time...
 
Re: Editing SQL Values

Brilliant! Thank you so so so much. I think i am going to take the same route as you. Bed time!

I will get the mysql/php integration sometime. I'm just not that experienced yet.

Once again thank you.


EDIT: If it's okay with the site owner, I will most definately put some form of credit somewhere on the site.
