PHP not posting information from database
(2 answers)
Closed 8 years ago.
I'm trying to add information to a database via PHP. However, when you submit the form it says "Error adding program." I've looked at the code and can't seem to find what's causing the error. Any advice?
Here's the form code:
<form name="Add" id="Add" method="post" action="programadd.php">
<p>Program Name:
<input name="program" type="text" id="program" />
</p>
<p>Air Date
<input name="air date" type="text" id="airdate" />
</p>
<p>Description
<input name="description" type="text" id="description" />
</p>
<p>Production
<input name="production" type="text" id="production" />
</p>
<p>Promotions
<input name="promotion" type="text" id="promotion" />
</p>
<p>Community
<input name="community" type="text" id="community" />
</p>
<p>Web
<input name="web" type="text" id="web" />
</p>
<p>
<input type="submit" name="Submit" value="Submit" />
</p>
</form>
And here's the code that adds the info into the db.
<?php require_once("db_connx.php");
$program = $_POST['Program'];
$airdate = $_POST['Air Date'];
$description = $_POST['Description'];
$production = $_POST['Production'];
$promotion = $_POST['Promotions'];
$community = $_POST['Community'];
$web = $_POST['Web'];
if (mysql_query ("INSERT INTO 'Content Calendar' (Program, 'Air Date', Description, Production, Promotions, Community, 'Web') VALUES ('$program', '$airdate', '$description','$production', '$promotion', '$community', '$web')"))
{ echo "Program successfully added to the database <br />";
}
else
{ echo "Error adding program"; }
require_once("db_connx_close.php");
?>

Answer 1

Do not use single quotes on column names , use backticks instead or let them be as it is.
The right way...
mysql_query ("INSERT INTO `Content Calendar` (`Program`, `Air Date`, `Description`, `Production`, `Promotions`, `Community`, `Web`) VALUES ('$program', '$airdate', '$description','$production', '$promotion', '$community', '$web')")
This (mysql_*) extension is deprecated as of PHP 5.5.0, and will be removed in the future. Instead, Prepared Statements of MySQLi or PDO_MySQL extension should be used to ward off SQL Injection attacks !

Answer 2

Here is the issues
INSERT INTO
'Content Calendar' <--
(
Program,
'Air Date', <--
Description,
Production,
Promotions,
Community,
'Web' <--
They should all be enclosed with `` as
INSERT INTO
`Content Calendar`
(
Program,
`Air Date`,
Description,
Production,
Promotions,
Community,
Web
Thumb rules :
if you have a table name or colum name as "Some Name" meaning a space
in between then you must enclose them with back ticks ``
If you are using any reserved keywords they also must be enclosed
within backticks

Answer 3

Change these lines
if (mysql_query ("INSERT INTO 'Content Calendar' (Program, 'Air Date', Description, Production, Promotions, Community, 'Web') VALUES ('$program', '$airdate', '$description','$production', '$promotion', '$community', '$web')"))
{ echo "Program successfully added to the database <br />";
}
else
{ echo "Error adding program"; }
To
if (mysql_query ("INSERT INTO `Content Calendar` (`Program`, `Air Date`, `Description`, `Production`, `Promotions`, `Community`, `Web`) VALUES ('$program', '$airdate', '$description','$production', '$promotion', '$community', '$web')"))
{ echo "Program successfully added to the database <br />";
}
else
{ echo "Error adding program"; }
