I'm trying to create a dropdown list with the values being populated from the database. In the following code, I have created a table for viewing the student details and created delete and add buttons to add and delete the information.
The problem is while adding the details for class id, I used a dropdown value from another table to be populate the values, but I was not able to do it.

You are closing the <td> inside the select:
Replace
echo "<td><select type=text name=classid></td>";?>
With
echo "<td><select type=text name=classid>";?>
And close the '</td>' after the '</select>'
Find out <td><select type=text name=classid></td> in your code and remove the ending tag </td> from it. After all the <option> ... </option> close the </td>

This way you can check error.
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
these are the codes
where do you think I should insert the header (Location:'home.php')
I tried using after the if statements, these are the codes
else {
try {
header('Location: home.php');
}
but it directly goes to home.php even when I haven't clicked the update button
<?php
if (isset($_POST['update'])){
$UpdateQuery = "UPDATE registry SET db_id = '$_POST[db_id]', db_name =
'$_POST[db_name]', db_age = '$_POST[db_age]', db_gender =

mysql_query($UpdateQuery);

You should add it after query is executed.
Here is the code
if (isset($_POST['update'])){
$UpdateQuery = "UPDATE registry SET db_id = '$_POST[db_id]', db_name =
'$_POST[db_name]', db_age = '$_POST[db_age]', db_gender =
'$_POST[db_gender]', db_birthdate = '$_POST[db_birthdate]', db_phone =
'$_POST[db_phone]', db_address = '$_POST[db_address]'
WHERE db_id = '$_POST[hidden]'";
mysql_query($UpdateQuery);
//redirect to home.php
header('Location: home.php');
}
I'm trying to is have have table to display my database with an update, delete, and add functions.
My problem is when I view it. It doesn't show the full text in the "Description" column and also in "Developer". Also in the "SecondDirectory" column it shows </td instead of just blank if its blank.

$UpdateQuery = "UPDATE table SE ID='$_POST[topic]',Filename='$_POST[filename]', Description='$_POST[description]', TopDirectory='$_POST[topdirectory]', SecondDirectory='$_POST[seconddirectory]', Developer='$_POST[developer]', Date='$_POST[date]' WHERE ID='$_POST[hidden]'";
mysql_query($UpdateQuery, $con);

mysql_query($DeleteQuery, $con);

So I figured it out.
echo "<td>" . "<input type=text name=description value=" . $record['Description'] . " </td>";
What I needed to put is a single quotation right after value= and two single quotations in " " so that it also counts the spaces. The code should have been...
echo "<td>" . "<input type=text name=description value='" . $record['Description'] . "'' </td>";
Dont mind the security issues, this is just local testing, but when ever i click the update button none of the changes go through on the page or on the query and i get no erros.
<?php
$link = mysqli_connect("localhost", "root", "", "test") or die("could not connect");
if (isset($_POST['update'])) {
$updateQuery = (" UPDATE `test1` SET f_name = '$_POST[f_name]', l_name='$_POST[l_name]', email='$_POST[email]' WHERE id='$_POST[id]'");
mysqli_query($link, $updateQuery);
};
$query = ("SELECT * FROM `test1`");
$result = mysqli_query($link, $query);
echo "<table border=1
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Email</th>
</tr>";
while($row = mysqli_fetch_array($result)) {
echo "<form method=post action=update.php>";
echo "<tr>";
echo "<td>" . "<input type=text name=f_name value=" . $row['f_name'] . " </td>";
echo "<td>" . "<input type=text name=l_name value=" . $row['l_name'] . " </td>";
echo "<td>" . "<input type=text name=email value=" . $row['email'] . " </td>";
echo "<td>" . "<input type=hidden name=id value=" . $row['id'] . " </td>";
echo "<td>" . "<input type=submit name=submit value=update" . " </td>";
echo "</tr>";
}
?>
change your form to
while($row = mysqli_fetch_array($result)) {
echo "<form method=post action=update.php>";
echo "<input type=hidden name=update>";
echo "<tr>";
echo "<td>" . "<input type=text name=f_name value=" . $row['f_name'] . " </td>";
echo "<td>" . "<input type=text name=l_name value=" . $row['l_name'] . " </td>";
echo "<td>" . "<input type=text name=email value=" . $row['email'] . " </td>";
echo "<td>" . "<input type=hidden name=id value=" . $row['id'] . " </td>";
echo "<td>" . "<input type=submit name=submit value=update" . " </td>";
echo "</tr>";
}
POST keys should be in quotes. Try this instead:
$updateQuery = "UPDATE test1 SET f_name = ".$_POST['f_name'].", l_name=."$_POST['l_name'].", email=".$_POST['email']." WHERE id=".$_POST['id'];
Try this:
$updateQuery = ("UPDATE `test1` SET f_name = '{$_POST['f_name']}', l_name='{$_POST['l_name']}', email='{$_POST['email']}' WHERE id='{$_POST['id']}'");
Also you can try echoing something inside your if (isset($_POST['update'])) { to make sure it is testing true.
Here is your problem:
if (isset($_POST['submit']) && $_POST['submit'] == 'update') {
The name of the submit button is submit not update, the value is update.
I am having a problem displaying content on a table from mysql table in the database to a form in PHP. My problem is that only the first word show on the address field for example.
Please look at my page on: http://www3.londonmet.ac.uk:8008/~iia0014/employeeManager.php
And also the cells are not aligned with the title.
Can anyone help me to solve this?
On my css I have:
table {
table-layout:fixed;
width:180%;
overflow:hidden;
border:1px ;
word-wrap:nowrap;
text-align:left;
}
But even if removing the CSS, just the first word appear.

<?php

$con = mysql_connect("$host","$username","$password");
if (!$con){
die("Can not connect: " . mysql_error());
}
mysql_select_db("$db_name",$con);
if(isset($_POST['update'])){

In the below quotes you were missing quotes and the tags were not closed proprely!
while($record = mysql_fetch_array($myData)){
echo "<form action='employeeManager.php' method='post'>";
echo "<tr>";
echo "<td><input type='hidden' name=hidden value='" . $record['EmpNo'] . "'> </td>";
echo "<td><input type='text' name='name' value='" . $record['Name'] . "'> </td>";
echo "<td><input type='text' name='dob' value='" . $record['DOB'] . "'> </td>";
echo "<td><input type='text' name='tel' value='" . $record['Tel'] . "'> </td>";
echo "<td><input type='text' name='address' value='" . $record['Address'] . "'> </td>";
echo "<td><input type='text' name='department' value='" . $record['Department'] . " </td>";
echo "<td><input type='text' name='payrate' value='" . $record['PayRate'] . "'> </td>";
echo "<td><input type='text' name='skills' value='" . $record['Skills'] . "'> </td>";
echo "<td><input type='text' name='gender' value='" . $record['Gender'] . "'> </td>";
echo "<td><input type='submit' name='update' value='update'> </td>";
echo "<td><input type='submit' name='delete' value='delete'> </td>";
echo "</tr>";
echo "</form>";
}
For better understanding of your mistake, notice your code:
echo "<td><input type=text></td>";
It should be like that:
echo "<td><input type='text'></td>";
It works, its just that you don't close the tag, which results in:
<input type=text name=address value=one two thre
The browser reads it as value=one and "two" and "three" like separate arguments.
What you need is a quote like this:
<input type=text name=address value="one two three"/>
