I'm trying to add form data into my database table on Xampp ,but while My echo displays everything properly ,it doesn't input anything into the database table and I wonder if I'm missing something here.I made sure to spell everything the same ,so I doubt it's a spelling error atleast....Any help,suggestions and or corrections are greatly appreciated !

hi your are checking value in insert isset($_POST['insert']) but insert name not assign in any control so assign insert name to your submit control check below :
<input type="submit" value="Submit" name="insert">
I'm kinda confused with your code but I think the wrong part is in here:
<input type="submit" name="submit" value="Submit">
You have this submit but look at this:
if(isset($_POST['insert']))
You are trying to check if POST is set to insert instead of submit.

I am attempting to display the results without the form being shown at the same time. So, initially when they go to the URL they see the form, and after they fill out the form and the form validation and required fields and URL is valid. Here is what I started with.

$TXTlinkname = $TXTurl = "";
if ($_SERVER["REQUEST_METHOD"] == "POST") {

$TXTlinknameErr = "Name is required";
} else {
$TXTlinkname = test_input($_POST["TXTlinkname"]);
// check if name only contains letters and whitespace
if (!preg_match("/^[a-zA-Z ]*$/",$TXTlinkname)) {
$TXTlinknameErr = "Only letters and white space allowed";
}
}
if (empty($_POST["TXTurl"])) {
$TXTurl = "";
} else {
$TXTurl = test_input($_POST["TXTurl"]);
// check if URL address syntax is valid (this regular expression also allows dashes in the URL)
if (!preg_match("/\b(?:(?:https?|ftp):\/\/|www\.)[-a-z0-9+&##\/%?=~_|!:,.;]*[-a-z0-9+&##\/%=~_|]/i",$TXTurl)) {

Here is what I have tried.
I've tried adding else statements after body and before results. I'd like the results not to show until after form submitted.
Here's what I have so far...
I tried to add the below after the body
<?php
//If form not submitted, display form.
if (!isset($_POST['submit'])||(($_POST['name']) == "")){
?>
Then I added:
<?php
} else {
//Retrieve show string from form submission.
Just after
// define variables and set to empty values
Finally added:
<?php
} ?>
Before /body
Here is what I tried.
<!DOCTYPE HTML>
<html>
<head>
<style>
.error {color: #FF0000;}
</style>
</head>
<body>
<?php
//If form not submitted, display form.
if (!isset($_POST['submit'])||(($_POST['TXTlinkname'] && $_POST['TXTurl']) == "")){
?>
<?php
// define variables and set to empty values
$TXTlinknameErr = $TXTurlErr = "";
$TXTlinkname = $TXTurl = "";
if ($_SERVER["REQUEST_METHOD"] == "POST") {
if (empty($_POST["TXTlinkname"])) {
$TXTlinknameErr = "Name is required";
} else {
$TXTlinkname = HTML_input($_POST["TXTlinkname"]);

So, initially when they go to the URL they see the form, and after they fill out the form and the form validation and required fields and URL is valid.
The big issue I see with your code is the if statement. The variables are not defined unless form hasn't been submitted. What I've changed is moved the function to be defined globally along with the variable names, and inverted the if statement. PHP Tags, you don't need them everywhere. One wrapper is good enough.
I'm not sure about what your result is, but for what you asked, I shall provide.

You have to have a variable that tells you if you're going to show the textarea or not...

in achievement am expected to redirect to error or index page but my code above refress back to first form what are my doing wrong. Big thanks in advance
My code is given below (didn't include any html, no error/warning/notice). The program executes fine. The only problem I have is when I try to change the member_id and date fields in database- it doesn't work! As you can see I have used separate names for same fields mmid (used in the form) for member_id and dd (used in the form) for today. So, when user enters a different value it is assigned to mmid and dd while keeping the original values to member_id and dd allowing me to properly execute the update query. All other fields update is done as expected. None of the fields in the db is primary/unique/index. Could you please help me find where the problem is?

I just started learning PHP today so im a beginner and im not very
familiar with it. trying to use php on a local host to make a booking
reservation page for a restaurant. What i was trying to do is make a
form and validate it so that the user wont be able to leave out any
required fields. however it doesnt seem to work. can anyone tell me
where i went wrong please ?
if there aren't any errors you have to check the name of the php file? does it have the extension ".php"?
Are you referring the right directory?
is the server running?
I am working on a project for school and I can't seem to figure out what is wrong with my html/php page.
For the record, I am making an html page with php and it is connected to an Oracle database.
I am trying to add a Person to the Person table but when I type in the information and click submit the form (the entire body of the page) completely disappears and the record is not added to the table. I have been looking online all day for an answer and it still does not work.
My code:
