I'm trying to create a text editing and updating capability to help
someone who wants to maintain content on a web page without having to
know any HTML or use a web authoring tool and FTP'ng the contents.
I've already created a screen whereby the person can create new
content with a PHP program that inserts into a MySQL table. But, I'm
having a little trouble in creating the edit/update functionality.
Can somebody help me out? Thanks.
I created an edit screen called "teach_edit.php ". Based upon some
search parameters on another HTML screen, it retrieves the appropriate
text from the database. It seems to allow on screen editing.
However, when I hit the Submit button, nothing happens. It's supposed
to call another program called "teach_update.p hp". Here's the code
for it.
<HTML>
<HEAD>
<TITLE>Teachi ng Edit Program</TITLE>
</HEAD>
<BODY>
<?php
@ $db = mysql_connect(' localhost', '<db name>', '<password>');
if (!$db)
{
echo "Error: Could not connect to database. Please try again
later.";
exit;
}
mysql_select_db ("<db>");
$query = "select * from albert where ".$searchty pe." like
'%".$searchterm ."%'";
$result = mysql_query($qu ery);
while ($row = mysql_fetch_arr ay($result)) {
$title = $row['title'];
$teaching = $row['teaching'];
$teaching = wordwrap($teach ing, 60, "\n", 1);
$teachnum = $row['teachnum'];
}
if ($result)
{
echo '<textarea name="teachnum" rows="1" cols="4"
wrap="off">';
echo htmlspecialchar s($teachnum)."\ n";
echo '</textarea>';
echo '<textarea name="title" rows="1" cols="60" wrap="off">';
echo htmlspecialchar s($title)."\n";
echo '</textarea>';
echo '<textarea name="teaching" rows="20" cols="80"
wrap="on">';
echo htmlspecialchar s($teaching)."\ n";
echo '</textarea>';
}
?>
<input type=submit value="Update" name="teach_upd ate.php">
</form>
</BODY>
</HTML>
The "teach_update.p hp" looks like this.
<HTML>
<HEAD>
<TITLE>Teachi ng Update Program</TITLE>
</HEAD>
<BODY>
<?php
@ $db = mysql_connect(' localhost', '<database>', '<password>');
if (!$db)
{
echo "Error: Could not connect to database. Please try again
later.";
exit;
}
mysql_select_db ("<db>");
$query = "update albert set title =". $title . " and teaching = ".
$teaching . " where teachnum =" . $teachnum ;
$result = mysql_query($qu ery) or die("Could not update!");
if ($result)
{
echo mysql_affected_ rows()." text item updated into
database.";
}
?>
</BODY>
</HTML>
