Trying to cater to past users on my blog

Trying to cater to past users on my blog - php

I am trying to cater to past users who have posted in the past. What I am trying to do is highlight any of the users pasts posts and also, on the home page do something like welcome back $name ! ONLY if the user has posted before though. I have no idea how to do this, need to check against the database probably but I am not sure how.
Thank you in advance.

How to use the php 'include' function in 'echo'ed content?

I have a process.php file for processing a comment/message form. If there is an error during the processing, the incorrect form content is echoed and shown as a web page named process.php to the viewer for correction and resubmitting.
The problem is that I need the echoed content to contain various <?php include("xxxx.php");?> elements so that it matches the rest of my site. But this seems to make the page fall over (showing blank page with no content). I've been told that I should use either include("xxxx.php"); or echo file_get_contents("xxxx.php"); from within the echoed content, but neither displays the intended content.
Any help in these issues would be greatly appreciated.
Code: (some items xxxxx for security)
<?php
// Information to be modified
$your_email = "xxxxxxxx#xxxxx.xx.xx"; // email address to which the form data will be sent
$subject = "Contact message"; // subject of the email that is sent
$thanks_page = "thankyou.htm"; // path to the thank you page following successful form submission
$contact_page = "mail_form_styled.php"; // path to the HTML contact page where the form appears
// Nothing needs to be modified below this line
if (!isset($_POST['submit'])) {
header( "Location: $contact_page" );
}
if (isset($_POST["submit"])) {
$nam = $_POST["name"];
$ema = trim($_POST["email"]);
$com = $_POST["comments"];
$spa = $_POST["spam"];

$nam = stripslashes($nam);
$ema = stripslashes($ema);
$com = stripslashes($com);

$error_msg=array();
if (empty($nam) || !preg_match("~^[a-z\-'\s]{1,60}$~i", $nam)) {
$error_msg[] = "The name field must contain only letters, spaces, dashes ( - ) and single quotes ( ' )";
}

$error_msg[] = "Your email must have a valid format, such as name#mailhost.com";

You'd simply use CSS as you normally would...
<?php
// index.php
?>
<!doctype html>
<html>
<head>
<style type="text/css">
.myClass {
color: #f00;
}
</style>
</head>
<body>
<?php
include('myFile.php');
?>
</body>
</html>
<?php
// included myFile.php
echo '<p class="myClass">Echoed content!</p>';
If you're ending up with a blank page with no content then you potentially have errors in your PHP. Ensure error reporting is enabled and you'll be able to see what's going wrong.

Using Strip Tags and check for empty fields PHP

So i have a form here, and I want on the to do some php so that if the field is empty, it will say once you submit the form after it loads to the post page, that sorry you entered no date. I also want to add strip tags, however I am unsure how, if they go on the posting_wall or if they go in the form.php? I want to use strip all tags.
I believe the empty validation was if(!empty(($date)) { echo "sorry you did not enter a date"; } but i could not get it to work.
Thank you in advance if you can help me with this. I will post the form.php and the posting wall below.

You can check through jquery in the submit function
var datepicker=$("#datepicker").val();
if(datepicker=='') { alert('Please enter date'); return false; }

It should be
if(empty(($date)) {
echo "sorry you did not enter a date";
}
NOT
if(!empty(($date)) {
echo "sorry you did not enter a date";
}
The first expression will print "sorry you did not enter a date" if the date field is empty. The second expression will print that message if the date field is not empty.
You can try the code below. It will print 'This is an empty string'
<?php
$date = '';
if (empty($date)) {
echo 'This is an empty string';
}
if (!empty($date)) {
echo 'The date is ' . $date;
}

Php errors, cant find where

I have this file that I need help fixing the errors I am gettng. I checked and it seems fine, but something must be wrong. The errors are

It means that the HTTP POST lack the 'name' key.
The error is explicit, if you edit the php file and go to line 62, you can understand.

You never set $name, you set $username.
Copyed and clipped from your code:
$username = strip_tags($_REQUEST['name']);
...
$post_fields['username'] = $name;

PHP logic error in a php form code

I'm unable to solve the logical error in the code. I'm not sure what is wrong though it seems the logic is correct
This is my php:

Errors:
Check this php fiddle here.
line 25. This is never shown even if I leave x textfield blank
$message = "You forgot to enter X Value";
same is with line 29. This is never shown even if I leave y textfield blank
$message = "You forgot to enter Y Value";
However if I enter the values in x and y textfield i.e. in txtXLocation and in txtYLocation they are being saved in db meaning it is just not checking the validation.
Thanks in advance

make sure you have connection.php file in includes folder and you have given correct path to reach that file.
