This one has completely blown my mind. I have a very basic understanding of PHP and hence my code is so wrong. My aim is to dynamically create a drop menu where users can select an entry from the database, which I have working. From that selection I have a form what I need to auto populate with the row data from the selection from the database. Could anyone help?
(Please note: I know my code is really bad, wrong etc and the deprecated tags. This is all for a college project)
<form id="edit" method="POST" action="">
<?php
$con = mysql_connect("localhost","root","");
if(!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db('flexiflash', $con);
$query = 'SELECT * FROM event';
$result = mysql_query($query);
echo "<select name='events' value='-'>\n";
echo "<option value='Select event'>Select an event to be changed\n";
while($row = mysql_fetch_row($result))
{
$eventSelect = $row[0];
echo "<option value='$eventSelect'>$row[1]</option>\n";
}
echo "</select>"
?>
<h1>
<button id="submit" type="submit">Delete</button>
</h1>
</form>
THE ABOVE PIECE OF CODE WORKS, BELOW IS NOT WORKING
<?php
if (isset($_POST['events']))
{
$eventselection = $_POST['events'];
$query = "SELECT * FROM events where event_name = '$eventselection'";
$row=mysql_fetch_array($query);
}
?>
<form name="editevents" method="POST">
<input type="hidden" value="<?php echo ($row['event_id']); ?>" name="id" />
<h1>
<label for="eventname">Event Name</label>
<input id="eventname" type="text" name="eventname" value="<?php echo ($row['event_name']); ?>" />
</h1>
<h1>
<label for="eventtime">Event Time</label>
<input id="eventtime" type="time" name="eventtime" value="<?php echo ($row['event_time']); ?>" />
</h1>
</form>
Remove value
attribute from drop-down and \\n
from you code . Close your default </option>
for Select an event to be changed
option. in second block of code you missing mysql_query
echo "<select name='events'>";
Corrected Block of code:-
<form id="edit" method="POST" action="">
<?php
$con = mysql_connect("localhost", "root", "");
if (!$con) {
die('Could not connect: ' . mysql_error());
}
mysql_select_db('flexiflash', $con);
$query = 'SELECT * FROM event';
$result = mysql_query($query) or die(mysql_error());
echo "<select name='events'>";
echo "<option value=''>Select an event to be changed</option>";
while ($row = mysql_fetch_row($result)) {
$eventSelect = $row[0];
echo "<option value='$eventSelect'>$row[1]</option>";
}
echo "</select>";
?>
<h1>
<button id="submit" type="submit">Delete</button>
</h1>
</form>
and
<?php
if (isset($_POST['events']))
{
$eventselection = $_POST['events'];
$query = "SELECT * FROM events where event_name = '$eventselection'";
$result = mysql_query($query);
$row=mysql_fetch_array($result);
