So I want to fetch my data from Database and be able to display and update it. Im on the part where I have to display a value from the db on a Dropdown but only the first option of the dropdown is being displayed.
Below is complete code.
<?php
mysqli_connect('localhost', 'root', '');
mysqli_select_db('storm');
$_GET['id'];
$ssh = $_GET['ssh'];
$_GET['provi'];
$_GET['impact'];
$_GET['advice'];
$_GET['date'];
$_GET['typhoon'];
$_GET['warning'];
?>
<html>
<body>
<div class="container">
<form action="edit.php" method="post">
<div class="form-group">
<label for="prov">Provinces</label><br>
<select id="prov" class="form-control" type="text" name="provi1">
<option value="Isabela"><?php echo $_GET['provi'];?></option>
<option value="La Union"><?php echo $_GET['provi'];?></option>
<option value="Pangasinan"><?php echo $_GET['provi'];?></option>
<option value="Ilocos Sur"><?php echo $_GET['provi'];?></option>
<option value="Ilocos Norte"><?php echo $_GET['provi'];?></option>
</select>
</div>
<div class="form-group">
<label>Date</label><br>
<input class="w3-input w3-border form-control" type="date" name="date" value="">
</div>
<div class="col-md-6">
<div class="form-group">
<label>Typhoon Name</label><br>
<input type="text" name="typhoon" value="<?php echo $_GET['typhoon']; ?>" class="form-control">
<input type="hidden" name="id" value="">
</div>
<div class="form-group">
<label>Warning #</label><br>
<input type="text" name="warning" value="<?php echo $_GET['warning']; ?>" class="form-control">
</div>
</div>
<div class="col">
<div class="form-group">
<input class="btnSubmit" type="submit" value="Update" name="submit" style="background-color: #408cff;">
<input class="btnSubmit" type="reset" value="Cancel" style="background-color: #de5959;">
</div>
</div>
</form>
<?php
if(isset($_GET['submit'])){
$id = $_GET['id'];
$ssh = $_GET['ssh'];
$muni = $_GET['muni'];
$impact = $_GET['impact'];
$advice = $_GET['advice'];
$date = $_GET['date'];
$typhoon = $_GET['typhoon'];
$warning = $_GET['warning'];
$query = "UPDATE twothree SET ssh='$ssh', muni='$muni', impact='$impact', advice='$advice', date='$date', typhoon='$typhoon', warning='$warning' WHERE id='$id'";
$data = mysqli_query($conn, $query);
if($data){
echo "Record Updated Successfully!";
}else{
echo "Record Not Updated.";
}
}
?>
I'm pretty sure that I am doing something wrong. Hope you guys figure it out for me. I'm new to this and I hope that I can learn from you guys. Thanks.
You can use something like this at basic level. this will retrieve all data from table and add a dropdown option to it.
<select class="" name="" required>
<option value="" selected disabled>Select a option</option>
<?php
$select_1 = $db->query("SELECT * FROM table");
while ($row_1 = $select_1->fetch_assoc()) {
?>
<option value="<?php echo $row_1['value']; ?>">
<?php echo $row_1['name']; ?>
</option>
<?php } ?>
</select>
where $db is your database connection and it must be mysqli connection.
You should do like this, to display the list of provinces.
<?php
$host = "localhost";
$user = "root";
$pwd = "";
$db = "storm";
$db_connection = new mysqli($host, $user, $pwd, $db);
if ($db_connection->connect_errno) {
printf("Connect failed: %s\n", $db_connection->connect_error);
exit();
}
//select provinces here
$provinces = $db_connection->query("Select * from provinces"); //change provinces according to your table name that you want to query.
?>
<div class="form-group">
<label for="prov">Provinces</label><br>
<select id="prov" class="form-control" type="text" name="provi1">
<?php
while ($row = $provinces->fetch_object()){
echo '<option value="'.$row->province_name.'">'.$row->province_name.'</option>'; //change province_name according to your fieldname.
}
?>
</select>
</div>
<?php
$db_connection->close();
?>
bro you need to loop data form your database to get continuous data out of your database you could use this.
<?php
$host = "localhost";
$user = "root";
$pwd = "";
$db = "storm";
$db_connection = new mysqli($host, $user, $pwd, $db);
if ($db_connection->connect_errno) {
printf("Connect failed: %s\n", $db_connection->connect_error);
exit();
}
//select provinces here
$query = mysqli_query($db_connection,"Select * from provinces");
?>
<div class="form-group">
<label for="prov">Provinces</label><br>
<select id="prov" class="form-control" type="text" name="provi1">
<?php
while ($row = mysqli_fetch_assoc($query)){
echo '<option value="'.$row["province_name"].'">'.$row["province_name"].'</option>'; //change province_name according to your fieldname.
}
?>
</select>
</div>
<?php
$db_connection->close();
?>
you code should look like this

if (mysqli_query($link, $sql)) {
exit();
} else {
echo "Error: " . $sql . "<br>" . mysqli_error($link);
}
how do I pass in value from selected option from to insert query in this code here. i have using row[] but the value is not passing on in the from to my insert query when I selected. in past i have tried POST['id'] but it select the same value as the id before.
Try changing line
echo "<option value=".$row['id']."name='product' >".$row['name']."</option>";
to
echo "<option value=".$row['id'].">".$row['name']."</option>"
$row['product'] doesn't exist - try changing the beginning of your php code to
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$id = $_POST['id'];
$product = $_POST['product'];

what is the issue in the code?
You need to connect to database first. After that you should run the query. Try following code
<div id="wrapper">
<div id="content">
<form action="<?php echo $_SERVER['PHP_SELF'] ?>" method="post">
<label>Title:</label>
<input type="text" name="title" />
<label for="body">Body:</label>
<textarea name="body" cols=50 rows=10></textarea>
<label>Category:</label>
<select name="category">
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "your_database_name_here";
$conn = new mysqli($servername, $username, $password, $dbname);
$query = $conn->query("SELECT * FROM categories");
while($row = $query->fetch_object())
{
echo "<option value='".$row->category_id."'>".$row->category."</option>";
}
?>
</select>
<br/>
<input type="submit" name="submit" value="Submit" />
</form>
</div>

I've tried creating a basic registration form (I'm pretty new to PHP).
The form works sometimes, but most of the times it's just sending blank entries into the MySQL database. Below is the code:
I have the following form:
<form action="#" method="post">
<h2 class="sub-heading-agileits">Participant 1</h2>
<div class="main-flex-w3ls-sectns">
<div class="field-agileinfo-spc form-w3-agile-text1">
<input type="text" name="name1" placeholder="Full Name" required="">
</div>
<div class="field-agileinfo-spc form-w3-agile-text1">
<select class="form-control" name="year1">
<option>Year</option>
<option value="1st Year">1st Year</option>
<option value="2nd Year">2nd Year</option>
<option value="3rd Year">3rd Year</option>
</select>
</div>
</div>
<div class="main-flex-w3ls-sectns">
<div class="field-agileinfo-spc form-w3-agile-text2">
<input type="text" name="phone1" placeholder="Phone Number" required="">
</div>
<div class="field-agileinfo-spc form-w3-agile-text2">

<div class="field-agileinfo-spc form-w3-agile-text">

</div>
<div class="field-agileinfo-spc form-w3-agile-text1">
<select class="form-control" name="year2">
<option>Year</option>
<option value="1st Year">1st Year</option>
<option value="2nd Year">2nd Year</option>
<option value="3rd Year">3rd Year</option>
</select>
</div>
</div>
<div class="main-flex-w3ls-sectns">
<div class="field-agileinfo-spc form-w3-agile-text2">
<input type="text" name="phone2" placeholder="Phone Number">

<div class="clear"></div>

</form>
I'm sorry for the long form code.
This is the PHP code to post the data to the database:
$servername = "localhost";
$username = "fic";
$password = "fic201718";
$dbname = "fic201718";
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$name1 = $_POST['name1'];
$year1 = $_POST['year1'];
$phone1 = $_POST['phone1'];
$college1 = $_POST['college1'];
$email1 = $_POST['email1'];
$name2 = $_POST['name2'];
$year2 = $_POST['year2'];
$phone2 = $_POST['phone2'];
$college2 = $_POST['college2'];
$email2 = $_POST['email2'];
$sql = "INSERT INTO identitytheft (Participant1Name,Participant1Year,Participant1Phone,Participant1College,Participant1eMail,Participant2Name,Participant2Year,Participant2Phone,Participant2College,Participant2eMail) VALUES ('$name1','$year1','$phone1','$college1','$email1','$name2','$year2','$phone2','$college2','$email2')";
$conn->query($sql);
if (!empty($_POST['name1'])) {
echo ("<script type=\"text/javascript\"> alert('Successfully Registered'); </script>");
}
However, the form sometimes inserts absolutely blank data into the database. It sometimes works though.
One thing that I have noticed is, I do not get blank rows if there are no special characters in the responses. My columns are set to utf8_unicode_ci (all of the columns). Could there be something wrong here?
Please help?
If your POST variables aren't empty and the data you see is what you expect then it isn't your form and most like your query. Use var_dump to check your post variables after the form submission.
var_dump($_POST);
The first thing I will note is that you current approach is susceptible to SQL injection, so you'll want to clean up your code. Look up prepared statments http://php.net/manual/en/mysqli.quickstart.prepared-statements.php.
I'll clean up your current query, which should work for you. I obviously don't have your database setup, so I can test it. You don't have to format it like I did and I don't usually format it this way unless I'm debugging -- it helps align the column names with the values.
<?php
$servername = "localhost";
$username = "fic";
$password = "fic201718";
$dbname = "fic201718";
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$name1 = $_POST['name1'];
$year1 = $_POST['year1'];
$phone1 = $_POST['phone1'];
$college1 = $_POST['college1'];
$email1 = $_POST['email1'];
$name2 = $_POST['name2'];
$year2 = $_POST['year2'];
$phone2 = $_POST['phone2'];
$college2 = $_POST['college2'];
$email2 = $_POST['email2'];
$sql = "INSERT INTO identitytheft (
Participant1Name,
Participant1Year,
Participant1Phone,
Participant1College,
Participant1eMail,
Participant2Name,
Participant2Year,

VALUES (

)";
$conn->query($sql);
if (!empty($_POST['name1'])) {
echo ("<script type=\"text/javascript\"> alert('Successfully Registered'); </script>");
}
?>
if(!empty($varname) && !empty($varname)){

you can add this similar type of code,as it works only when the input fields are not empty and does not post non empty data into your database
Hi I created an rsvp form using bootstrap and PHP. I am new to PHP and database connections so I just wanted to confirm that I am doing it correctly. Am I using the correct syntax, is it safe from hacks (SQL injections), etc. Thanks.
Here is my PHP:
<?php
$servername = "rsvp.db";
$username = "******";
$password = "******";
$dbname = "rsvp";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
function test_input($data) {
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
return $data;
}
if(isset($_POST["submit"])){
$serverrsvp = test_input($_POST["formrsvp"]);
$serverattend = test_input($_POST["formattend"]);
$serverfullname = test_input($_POST["formfullname"]);
$serveremail = test_input($_POST["formemail"]);
$serverguests = test_input($_POST["formguests"]);
$serverguestnames = test_input($_POST["formguestnames"]);
$serverextras = test_input($_POST["formextras"]);
$serverrsvp = mysqli_real_escape_string($conn, $serverrsvp);
$serverattend = mysqli_real_escape_string($conn, $serverattend);
$serverfullname = mysqli_real_escape_string($conn, $serverfullname);
$serveremail = mysqli_real_escape_string($conn, $serveremail);
$serverguests = mysqli_real_escape_string($conn, $serverguests);
$serverguestnames = mysqli_real_escape_string($conn, $serverguestnames);
$serverextras = mysqli_real_escape_string($conn, $serverextras);
$sql = "INSERT INTO rsvp (dbrsvp, dbattend, dbfullname, dbemail, dbguests, dbguestnames, dbextras)
VALUES ('$serverrsvp', '$serverattend', '$serverfullname', '$serveremail', '$serverguests', '$serverguestnames', '$serverextras')";
if ($conn->query($sql) === TRUE) {
echo "<script type= 'text/javascript'>alert('Thank you for your RSVP');</script>";
} else {
echo "<script type= 'text/javascript'>alert('Error: " . $sql . "<br>" . $conn->error."');</script>";
}
$conn->close();
}
?>

I am using Unique Key for the field 'name', but when I update the record using edit file through admin, it gives me an error for duplicate entry. I can't remove unique key, it's required..

$query = "UPDATE tplus_torrentlist SET name = '$name', size = '$size', link = '$linkt', seeds = '$seeds', leechs = '$leechs', active = '$active'";
$result = mysqli_query($link, $query) or die(mysqli_error($link));
$error = mysqli_error($link);

Any solution without removing unique key from the field 'name' ?
Your update query need to correct as following -
$query = "UPDATE tplus_torrentlist SET name = '$name', size = '$size', link = '$linkt', seeds = '$seeds', leechs = '$leechs', active = '$active' WHERE id = $id limit 1";
