I'm trying to register the e-mail entered in my form by users in my SQL table. but I'm not receiving any errors and the data are not saved either!
<?php
echo "I was here !!!";
if(!empty($_POST['mail']))
{
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "mailing";
echo "I was here !!!";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = 'INSERT INTO contact VALUES ("","'.$_POST['mail'].'")';
if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
}
?>
and my html code:
<div class="form">
<p>Rester notifié par toutes les nouveautés !</p>
<form method="post" action="index.php" class="mainform">
<div class="field"><input type="text" class="field" name="mail" /></div>
<div class="submit"><input class="submit" type="button" value="Envoyer" /></div>
</form>
</div>
can you tell me what's the problem ?
change your button type .because if you want to submit the data by form then button type should be submit like that
<input class="submit" type="submit" value="Envoyer" />
Check if there's a value for $_POST['mail']. Your condition didn't handle empty value for $_POST['mail']. If there is a value. Change your query
INSERT INTO contact(email) VALUES ("'.$_POST['mail'].'")
Try this. Since you only need to add an email. Hope it helps.

"I have read a lot of problem been solved in stackoverflow similar to my problem, and have seen a lot of example, yet still my code is not inserting in to mysql. however if i hard feed the php it would insert. my info is coming as submit from html post.I have good server connection and also connection to the database, can any one help me if i miss any thing. here is my code below."
<?php
$servername = "localhost";
$username = "root";
$password = "";
$db="image";
// Create connection

echo $name;
echo $image;
if($name !=''||$image !=''){
//Insert Query of SQL

" i expect output of 5/2 to be 2.5"
Write the name for submit button
<input type="submit" name="submit" />
then in php file
if(isset($_POST['submit'])){ // Fetching variables of the form which travels in URL
}
this if statement will run
you not given name attribute to button so give name="submit" and if you want to upload file then change type="file"
<?php
$servername = "localhost";
$username = "root";
$password = "";
$db="image";
// Create connection
$connection = mysqli_connect($servername, $username, $password, $db); // Establishing Connection with Server

echo "Connected successfully";

if(isset($_POST['submit'])){ // Fetching variables of the form which travels in URL
$name = $_POST['name'];
$image = $_POST['image'];
echo $name;
echo $image;
if($name !=''||$image !=''){
//Insert Query of SQL
$query = mysqli_query("INSERT INTO image (id, name, imagename) VALUES ('NULL', '$name', '$image')");

You're checking isset($_POST['submit']) but there is no input field which is posted with submit name.. you need to add the name attribute in the submit button. also you're not passing the $connection in the mysqli_query.
$servername = "localhost";
$username = "root";
$password = "";
$db="image";
// Create connection
$connection = mysqli_connect($servername, $username, $password, $db); // Establishing Connection with Server
if (!$connection) {
die("Connection failed: " . mysqli_connect_error());
}
else{
echo "Connected successfully";
}
if(isset($_POST['submit'])){ // Fetching variables of the form which travels in URL
$name = $_POST['name'];
$image = $_POST['image'];
echo $name;
echo $image;
if($name !=''||$image !=''){
//Insert Query of SQL
$query = mysqli_query($connection, "INSERT INTO image (id, name, imagename) VALUES ('NULL', '$name', '$image')");
if($query !== false){
echo "Data Inserted successfully...!!";
}
else{
echo "Query failed";
}
}
else{
echo "Insertion Failed <br/> Some Fields are Blank....!!";
}
}
mysqli_close($connection); // Closing Connection with Server
?>
<form action = "test2.php" method="POST" enctype="multipart/form-data">
<label>name: </label><input type="text" name="name" />
<label>File: </label><input type="text" name="image" />
<input type="submit" name = "submit" />

One more suggestion always use PDO in code to prevent SQL injection. Your code is vulnerable to sql injection.
I am new to programing. I have one form to create Groups. It has two text fields Code Id and Code description. After submitting it showed me that the Code Id which i entered is already exist and if not it add one record in MySQL table.

values('$codigo','$nombre')");
if(mysqli_affected_rows($conn)>0){
echo "<p><h1><b>Grup $nombre added</h1></b></p>";

Please help me.
You are getting already exist message so that may be confirm that there is another data with same id. For further assistance please knock me
I'm trying to add a string to my database, where I have two columns: "id" and "image". The "id" column is supposed to increment and the "image" column should get a string. This is my phpcode:
<?php
$servername = "somename";
$username = "someusername";
$password = "somepssword";
$dbname = "somedatabase";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$image = $_POST["image"];
$sql = "INSERT INTO photos (image) VALUES ('$image')";
if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
?>
the html form:
the html form:
<body>
<form method="post" action="phpcode.php">
<input type="text" name="message" size="55">
<input type="submit"name="submit" value="Send">
</form>
</body>
</html>
I use this app to send a post to the server: https://www.getpostman.com/ yet for some reason it only increments a value id and doesn't receive anything for image like here:
enter image description here
<form method="post" action="phpcode.php">
<input type="text" name="message" size="55">
<input type="submit"name="submit" value="Send">
</form>
As suspected, your name attribute field is wrong as it does not correspond to what you are trying to post .
Change to
<form method="post" action="phpcode.php">
<input type="text" name="image" size="55">
<input type="submit"name="submit" value="Send">
</form>
When submitting forms, PHP reads from your "name" attribute on your form. That is what you are posting to your controller file.
I´m trying to create a form connected to a database but when I fill out the form and I refer to the table in phpMyAdmin I see that it have entered a blank record instead of form data. I´m using PhpStorm.
I think all this code is correct...
That is the form of the .html:
<form id="form1" name="form1" method="post" action="index.php">
<label for="userSignUp">Email</label>
<input type="text" name="userSign" id="userSignUp" />
<label for="passwordSignUp">Password</label>
<input type="password" name="passwordSign" id="passwordSignUp" />
<input type="submit" name="Submit" id="Submit" value="Submit" />
</form>
I have the following .php:
<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "test";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$db_selected = mysqli_select_db($conn, $dbname);
$userSignUp = ""; // If I substitute "" with characters at this time the table is well updated
$passwordSignUp = ""; // Same as before
if(isset($_POST['userSign'])){
$userSignUp = $_POST['userSign'];
}
if (isset($_POST['passwordSign'])) {
$passwordSignUp = $_POST['passwordSign'];
}
$sql = "INSERT INTO test.person (FirstName, Password) VALUES ('$userSignUp', '$passwordSignUp')";
if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();

You're missing the name tag on your submit. When data is POST'ed to the server, it uses the name tag.
<input type="submit" id="submit" name="Submit">
Remember to watch your Capitals also - (since you're checking if Submit is SET then you need to POST the submit).
You could just do:
if(isset($_POST['text'])) {
Also, going off the comments: I'd suggest taking a look at this link because you're prone to SQL Injections.
when we are going to post a form using POST or GET. we should always give name to all our fieds so we get get them just using $_POST['name'] or $_GET['name']. In Your case just give a name to your submit tag and check whether data is submitted or not.
replace
<input type="submit" id="Submit" />
with
<input type="submit" id="submit" name="submit">
and check it like
if(isset($_POST['submit'])) {// it will only check where form is posted or not
// your code...
}
