I cannot figure out why the dynamic dropdown won't populate from my database.:
<!doctype html>
<html>
<body>
<h2>Insert Album</h2>
<form action="insertalbum.php" method="POST">
Title: <input type="text" name="atitle" maxlength='50' required><br>
Band: <select name='bands'>
<?php
$conn = mysqli_connect("Server","database","password","username"); //i put in these placeholder for my actual credentials
// Check connection
if(mysqli_connect_errno()){
echo nl2br("Failed to connect to MySQL: " . mysqli_connect_error() . "\n ");
}
$query = "SELECT DISTINCT name FROM band";
$result = mysqli_query($conn, $query);
while ($row = mysqli_fetch_assoc($result)) {
unset($name);
$name = $row['name'];
echo '<option value="name"> $name </option>';
}
?>
</select>
<br>
Published Year: <input type="number" name="pyear" min='1900' max='2020' required><br>
Publisher: <input type="text" name="pname" maxlength='50' required><br>
Format:<select> <option value="record"> Record </option>
<option value="cd"> CD </option>
<option value="casette"> Casette </option>
</select> <br>
Price: <input type="number" name="price" min='0' max='9999.99'><br>
<input type="submit" value="Insert">
</form>
</body>
</html>
this a example:
<select id="employee">
<option value="" selected="selected">Select Employee Name</option>
<?php
/* connection */
$conn = mysqli_connect("Server","database","password","username");
/* query */
$sql = "SELECT id, employee_name, employee_salary, employee_age FROM employee LIMIT 10";
/* get data from db */
$resultset = mysqli_query($conn, $sql) or die("database error:". mysqli_error($conn));
/* build your dropdown*/
while( $rows = mysqli_fetch_assoc($resultset) ) {
?>
<option value="<?php echo $rows["id"]; ?>"><?php echo $rows["employee_name"]; ?></option>
<?php } ?>
</select>

I have a problem with multiple wheres in a consult to database mysqli. I don't know how to make it. I'm reading about JOINS for multiple consults, but I don't know it very well, and it still doesn't work. This is my code:
$status = mysqli_escape_string($con, $_POST['status']);
$type = mysqli_escape_string($con, $_POST['type']);
$beds = mysqli_escape_string($con, $_POST['beds']);
$baths = mysqli_escape_string($con, $_POST['baths']);
$query = "SELECT * FROM properties WHERE beds LIKE '%".$beds."%' OR baths LIKE '%".$baths."%' " ;
I need to obtain all results that have beds, baths, status, types, etc, but it does not work with the actual SELECT. I already made some tries with JOINS, but that did not work the way I expected. This function gives all the results but not filtered. Thank you for any help!
EDIT:
This is all my code, my form
<form action="" id="amenities-form" name="amenities-form" data-name="Amenities Form" class="top-search-form-left" method="POST">
<select id="status" name="status" data-name="status" class="select-search-form w-select">
<option value="sale">For Sale</option>
<option value="rent">For Rent</option>
</select>
<select id="type" name="type" data-name="type" class="select-search-form w-select">
<option value="">Type of property</option>
<option value="condo">Condo</option>
<option value="house">House</option>
<option value="commercial">Commercial</option>
<option value="lot">Lot</option>
<option value="villa">Villa</option>

This is my code of php
if (!empty($_POST)) {
$con = new mysqli($host, $user, $pass, $db);
if (mysqli_connect_errno()) {
printf("Falló la conexión failed: %s\n", $con->connect_error);
exit();
}
if (isset($_POST['search'])) {
$search = mysqli_escape_string($con, $_POST['search']);
$query = "SELECT * FROM properties WHERE title LIKE '%".$search."%'" ;
}else{
$status = mysqli_escape_string($con, $_POST['status']);
$type = mysqli_escape_string($con, $_POST['type']);
$beds = mysqli_escape_string($con, $_POST['beds']);
$baths = mysqli_escape_string($con, $_POST['baths']);
$query = "SELECT * FROM properties WHERE beds LIKE '%".$beds."%' OR baths LIKE '%".$baths."%' " ;
}
$res = $con->query($query);
if (!$res) {
trigger_error('Invalid query: ' . $con->error);
}
if ($res->num_rows) {
while ($row = $res->fetch_object()) {
//$status_name = $con->query("SELECT * FROM status WHERE id = {$row->status_id}");
//$status_name = $status_name->fetch_object();
//echo "{$row->title} ({$status_name->title})<br>";
echo "{$row->title} ({$row->status_id})<br>";
}
}else{
echo "No results";
}
$res->free();
$con->close();
}else{
echo 'No results';
}
I will try some suggest you did
I want a first radio button to be checked by default. When I click get schedule I want to fetch the schedule of that radio selected train number using a WHERE clause.
<?php
while ($res = mysql_fetch_array($result)) {
echo "<tr>";
echo "<td><input type = radio />" . $res['Train_no'] . "</td>";
?>
<form action="schedule.php" method="POST" class="form-inline">
<input type="submit" value="Get Schedule"/>
</form>
<?php
}
<?php
$con = mysql_connect("localhost", "root", "");
if ($con) {
$db = mysql_select_db('traindb', $con);
} else {
die('Could not connect: ' . mysql_error());
}
$selected_val = $_POST['Train_no']; // Storing Selected Value In Variable
echo "You have selected :" . $selected_val; // Displaying Selected Value
$result = mysql_query("SELECT * FROM train_detail WHERE Train_No='$selected_val'");
mysql_close($con);
?>
You can try this:
if(isset($_POST['Submit'])){
$selected_val = $_POST['Train_no']; // Storing Selected Value In
echo "You have selected :" .$selected_val; // Displaying Selected Value
$result = mysql_query("SELECT * FROM train_detail WHERE
Train_No='$selected_val'");
}
Here is one example of "select":
<form action="" method="post">
<select type="age" class="form-control" id="age" name="age">
<!-- <option value="disable" selected="">Please Select</option> -->
<option value="">Please select</option>
<option value="Under 35">Under 35</option>
<option value=">35 - 44">35 - 44</option>
<option value=">45 - 54">45 - 54</option>
<option value=">55 - 59">55 - 59</option>
<option value=">60 - 64">60 - 64</option>
<option value=">65 - 69">65 - 69</option>
<option value=">70 - 74">70 - 74</option>
<option value=">75 - 79">75 - 79</option>
<option value="80 +">80 +</option>
</select>
<input type="submit" value="Submit">
</form>
<?php
$age = $_POST['age'];
if (isset($_POST['age']) && $_POST['age'] == "")
echo "You did not choose any options. Pls try again.";
else {
echo $age;
}
?>
If you want embed PHP in select options, do it like this:
<option value="<?php echo $res['Train_no'] ?>"><?php echo $res['some_other'] ?></option>
For radio button it is like this:
<!DOCTYPE html>
<html>
<body>
<form action="/action_page.php">
<input type="radio" name="gender" value="<?php echo $res['Train_no'] ?>" checked><?php echo $res['some_other'] ?><br>
<input type="radio" name="gender" value="female"> Female<br>
<input type="radio" name="gender" value="other"> Other<br><br>
<input type="submit">
</form>
</body>
</html>
Okay i have this SQL statement for update which works find but I want to add locations which is in te_venue table after adding the location into sql i want for locations to be a drop down list which user can pick one location from list and when clicked on update it should update.
This is the php code that I have already (I need to add location into this)
<?php
$eventID = $_GET['id'];
if(isset($_POST['submit']))
{
$title = $_POST['title'];
$startdate = $_POST['startdate'];
$enddate = $_POST['enddate'];
$price = $_POST['price'];
$description = $_POST['description'];
$sql = "UPDATE te_events SET eventTitle='$title',eventStartDate='$startdate',eventEndDate='$enddate',eventPrice='$price',eventDescription='$description' WHERE eventID=$eventID";
if ($conn->query($sql) === TRUE)
{
header('Location:edit.php');
}
else
{
echo "Error updating record";
}
}
$sql = "SELECT * FROM te_events where eventID='$eventID'";
$result = $conn->query($sql);
while($row = $result->fetch_assoc())
{
$eventTitle = $row['eventTitle'];
$eventDescription = $row['eventDescription'];
$eventStartDate = $row['eventStartDate'];
$eventEndDate = $row['eventEndDate'];
$eventPrice = $row['eventPrice'];
}
?>
And this is where i want to have a drop down list for location.
<form method="post" action="">
<label for="title">Title</label><br/>
<input type="text" name="title" required/ value="<?php echo $eventTitle; ?>"><br/>
<label for="startdate">Start Date</label><br/>
<input type="date" name="startdate" required/ value="<?php echo $eventStartDate; ?>"><br/>
<label for="enddate">End Date</label><br/>
<input type="date" name="enddate" required/ value="<?php echo $eventEndDate; ?>"><br/>
<label for="price">Price (£)</label><br/>
<input type="number" step="any" name="price" required/ value="<?php echo $eventPrice; ?>"><br/>
<label for="description">Description</label><br/>
<textarea name="description" cols="55" rows="5"><?php echo $eventDescription; ?></textarea><br/>
<input type="submit" name="submit" value="Update" class="button">
</form>
Here is a screenshot of my tables too it might help.

I have created a form which allows users to edit existing data within a database, I pull information from one page to the next to populate text boxes and select boxes. I have managed to populate the select box with the correct value but when the update statement goes through it deletes or doesn't recognize the pre-existing value. Can anyone help?
if (isset($_POST['submit'])) {
// Process the form
if (empty($errors)) {
$id = $brand["brandId"];
$brandName = mysql_prep($_POST["brandName"]);
$brandCategory = mysql_prep($_POST["brandCategory"]);
$brandKeyword = mysql_prep($_POST["brandKeyword"]);
$addedBy = mysql_prep($_SESSION['username']);
$query = "UPDATE brands SET ";
$query .= "brandName = '{$brandName}', ";
$query .= "brandCategory = '{$brandCategory}', ";
$query .= "brandKeyword = '{$brandKeyword}', ";
$query .= "addedBy = '{$addedBy}', ";
$query .= "dateTime = CURRENT_TIMESTAMP ";
$query .= "WHERE brandId = '{$id}' ";
$query .= "LIMIT 1";
$result = mysqli_query($connection, $query);
if ($result && mysqli_affected_rows($connection) == 1) {
// Success
$_SESSION["message"] = "Brand updated.";
redirect_to("search.php");
} else {
// Failure
$_SESSION["message"] = "Brand update failed.";
}
}
} else {
// This is probably a GET request
} // end: if (isset($_POST['submit']))

</div>
The best way is to build the select from an array.
For instance:
<?php
$array = array('Animation', 'Automotive', 'Beauty and Fashion ', ...);
echo '<select class="textbox" id="bcategory" type="text" name="brandCategory">';
foreach ($array as $value){
if($value == htmlentities($brand["brandCategory"]){
echo '<option value='.$value.' selected>'.$value.'</option>';
}else{
echo '<option value='.$value.'>'.$value.'</option>';
}
}
echo '</select>;
This way you can check if the value in the array is the same that the one recieved by post and then add the selected attribute to the option tag.
Using AJAX How can I generate selections for a dropdown menu based on records available in a database?.
How can then use these selections to prefill a form with record/row data from a database when selected?
Heres a mock up I created of what I'm trying to do:
http://oi58.tinypic.com/2urb2ae.jpg
PHP FILE: contact_form.php
-----------------------------------------------------------
<?php
define('DB_NAME', 'xxx');
define('DB_USER', 'xxx');
define('DB_PASSWORD', 'xxx');
define('DB_HOST', 'xxx');
$connection = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD);
if(!$connection){
die('Database connection failed: ' . mysqli_connect_error());
}
$db_selected = mysqli_select_db($connection, DB_NAME);
if(!$db_selected){
die('Can\'t use ' .DB_NAME . ' : ' . mysqli_connect_error());
}
echo 'Connected successfully';
if (isset($_POST['itemname'])){
$itm = $_POST['itemname'];
}
else {
$itm = '';
}
if($_POST['mile']){
$mi = $_POST['mile'];
}else{
echo "Miles not received";
exit;
}
if($_POST['email']){
$email = $_POST['email'];
}else{
echo "email not received";
exit;
}
$sql = "INSERT INTO seguin_orders (itemname, mile, email)
VALUES ('$itm', '$mi', '$email')";
if (!mysqli_query($connection, $sql)){
die('Error: ' . mysqli_connect_error($connection));
}
CONACT FORM: formz.php
------------------------------------------------------------------------------
<html>
<header>
</header>
<body>
<form action="/demoform/contact_form.php" class="well" id="contactForm" method="post" name="sendMsg" novalidate="">
<big>LOAD PAST ORDERS:</big>
<select id="extrafield1" name="extrafield1">
<option value="">Please select...</option>
<?php
$email = $_POST['email'];
$query="select * from tablename WHERE email={$_POST['email']}";
$res=mysqli_query($connection,$query);
while($row = mysqli_fetch_assoc($res))
{
?>
<option value="<?php echo $row['fieldname']; ?>"><?php echo $row['fieldname']; ?></option>
<?php
}
?>
</select>
</br>
<input type="text" required id="mile" name="mile" placeholder="Miles"/>
</br>
<input id="email" name="email" placeholder="Email" required="" type="text" value="demo#gmail.com" readonly="readonly"/>
</br>
<input id="name" name="itemname" placeholder="ITEM NAME 1" required="" type="text" />
</br>
<input type="reset" value="Reset" />
<button type="submit" value="Submit">Submit</button>
</form>
</body>
</html>
Using an exemple, let's assume you want to fill the "name" select based on the option selected at the "gender" select:
<select name="gender" id="gender">
<option value="m">Male</select>
<option value="f">Female</select>
</select>
When nothing is selected yet, the "name" select is empty:
<select name="name" id="name">
<option value="NULL">Please select a gender first</option>
</select>
So, what you gotta do is: when the gender select got some selection, you populate the name select with values based on the gender select option.
$(document).ready(function() {
$('select#gender').change(function(){
$('select#name').load('LOAD_NAMES_BASED_ON_GENDER.php?gender='+$(this).val());
});
});
And your PHP file responsible for loading the names based on gender should look like:
$gender = $_GET['gender'];
$list = // the way you retrieve your list of names from your DB
And then you loop this $list into an list of options, such like:
foreach($list as $key=>$value)
echo '<option value="$key">$value</option>';
This simple.
PS: the load() function is kind of an alias for the $.ajax request, given that the only purpose here is to retrieve data.
