Getting these hyperlinks right and mixing HTML with PHP seems to be a constant source of sorrow for me. Whats wrong with this hyperlink?
echo '$suggestion[$ss_count]<br>;


it should be
echo ''.$suggestion[$ss_count].'<br>';
Within single quotes variables are not interpolated so you have to pull the link text out of the string literal.


try it ..!!
echo ''.$suggestion[$ss_count].'<br>';


you all missing the point.
JUST USE BACKSLASH

Its because characters after backslash are escaped by the PHP interpreter.
You can replace your code with the following :
XO/YEr\\fae?3

Can someone please explain to me what this piece of php code means.
echo "<a href='product.php?product_id".$product_id."'>
Is it saying that the link is taken from a variable from the product.php page and its named $product_id?

This is a GET parameter in the URL (it's also wrong btw). Say $product_id = 1.
echo "<a href='product.php?product_id".$product_id."'>
This would be "product.php?product_id1"
echo "<a href='product.php?product_id=".$product_id."'>
This would be "product.php?product_id=1", which would would handle by using
$_GET["product_id"]; //yields 1

Ths snippet outputs an HTML <a> tag. The $product_id is a variable, and echo is the command to output a string.
But I'd recommend to follow some basic Tutorials about HTML and PHP, as these are some of the most basic things.

I can’t display a variable like {{foo_bar}}, but if I change the name to fooBar it works. How can I display variables that contain underscores?

I think it's okay if you display variables that contain underscores. There is no error with it.

mysql_query("insert into user_info(Name,Id,Password,Email,Gender,Date_of_birth) values('".$name."','".$iden."','".$pass1."','".$email."','".$gender."','STR_TO_DATE('$date','%d,%m,%Y')')");
Can anyone tell which part of this code is incorrect, as it is not entering anything in the database.....

Unquote the 'STR_TO_DATE('$date','%d,%m,%Y')' call. I also cleaned up the rest of the code a bit. As a result you get:
mysql_query("insert into user_info(Name,Id,Password,Email,Gender,Date_of_birth) values('$name','$iden','$pass1','$email','$gender',STR_TO_DATE('$date','%d,%m,%Y'))");

On this part:
'STR_TO_DATE('$date','%d,%m,%Y')'
There are single quotes inside single quotes, causing an error. To fix this, replace the single quotes on the arguments to escaped double quotes, like this:
'STR_TO_DATE(\"$date\",\"%d,%m,%Y\")'
However, since you probably want to use the function and not post it literally, you should just remove the outside quotes, like this:
STR_TO_DATE('$date','%d,%m,%Y')

On THIS PAGE, I have the word "category =" before my campaigns.
My problem is: I am unable to find the code that can display the page id as shown in the url.
How can I get this to echo the page id as shown in the URL? to say "category = FREE".
can someone please help me.
thank you.

echo "category = ", htmlspecialchars($_GET['id']);

Any URL parameter can be retrieved using $_GET["param_name"], in your case: $_GET["id"]. You can save that as a variable, or echo it right away.
