which is used to get data from the database tables and output results.

I want href link for each of my results and on the click, it should download a file from ./"URL" column from a database table.
My database looks like this:
AND MY CURRENT PAGE IS http://mss1996.ddns.net:8008/files
I tried adding < a href=".$row["URL"]."> in outpur'array' but it destroys my page.
You should be able to easily add the URL field to form a valid URL if the contents of that field is indeed a valid URL. What I see missing form your code is http or https if it's an external link. If it's a relative link within the page then you're ok. Then add the </a> to close the link. So you'd form your table column like this:
echo '<td>' . $row["URL"] . '</td>';

I created a web-page,where you can search plant's scientific name. Type plant name in search_text it will give you results in search_result(live search like google and facebook search bar) . Ex: when you will type C in search input, in search result you will get C related search. Like C typed in search input, in search result it will start showing Cucumber(Cucumis sativus), Capsicum(Capsicum annuum), etc.
Now I want when you will click on Cucumber(Cucumis sativus) in search result, it have to direct to home.php/Cucumber . Or when user click on Capsicum(Capsicum annuum), it have to direct on home.php/Capsicum .
And on home.php in body tag I want to display plant name with their scientific name. And in para tag information related to plant search result.

echo '<a herf="home.php/">' . $output . '</a></div>';
?>
There are many ways of doing this
Passing the name of the plant as a GET param is not an option?
You could do
echo "<a href='home.php?plantname={$plantname}' target='_blank'>{$output}</a></div>";
As the response of your server, that would create the link and in home.php you retrieve the plant name with $_GET['plantname'].
in home.php you do
if(isset($_GET['plantname'])){
echo $_GET['plantname'];
}
Please correct this line in index.php

i'm trying to create an autocomplete box for a form.
Basically what I want to achieve is a textarea field that allows me to search the database for names belonging to a table and add them to a table through a form.
I managed to create this, but it allows me to search only one name at a time, while I would need to look for more names to add to the same textarea.
Basically I have a textarea and this must give me the possibility to insert more names:
name1
name2
...
Where each name is chosen from the drop-down menu that is created. In this way I could go to insert more "names" in the database.

In your opinion how can i do??
Thank you for your attention and for your time.
I checked a lot of articles and I don't understand it how to insert data into a MySQL table. What is wrong? I guess that my Ajax request is already wrong.
I would be happy to get help!!!
I did not write programs since 20 years. My coding is for sure not good, but I need to get it running.
Any help would be very appreciated!
The code that follows does not INSERT INTO and does not UPDATE. Why?

And here is the php script it talks to:
http://pastebin.com/tQppn84s
<?php
//connect to database
require ("config/config.php");
//get the username
$email = mysql_real_escape_string($_POST['email']);
//mysql query to select field username if it's equal to the username that we check '
$result = mysql_query('select email from refer where email = "'. $email .'" AND referred = "true"');
$row = mysql_fetch_array($result);
$usercheck = $row['username'];
//if number of rows fields is bigger them 0 that means it's NOT available '
if(mysql_num_rows($result)>0){
//and we send 0 to the ajax request
echo 0;
}else{
//else if it's not bigger then 0, then it's available '
//and we send 1 to the ajax request
echo 1;
}
?>
and $usercheck should check for the username.
You just need to change the formatting of the response, and modify how it's handled on receipt. For instance, instead of just echo 0; you could do something like (I wasn't sure how you wanted username used, so that was just a guess)
echo '{"available":false, "username":"'.$usercheck.'"}';
then, in your HTML page, you would
$.post("check_email.php", { email: email },
function(result){
response=jQuery.parseJSON(result);
//if the result is 1
if(response.available){
//show that the username is available
$('#email_availability_result').html('<span class="is_available"><b>' +email + '</b> is Available</span>');
}else{
//show that the username is NOT available
$('#email_availability_result').html('<span class="is_not_available"><b>' +email + '</b> has already been referred by user '+response.username+'</span>');
});
and, for the IS available case, you'd
echo '{"available":true}';
I'm learning PHP and JavaScript, and I'm building a blogging platform. I'm working on the comment system. I want to check if the name field matches any users in the database, and if it does, then I want to display a message that the name is taken.

echo 'Comment Sent!';
}
}
?>
I tried using $.ajax in the script tags, but it seems to do nothing. Can I get an example of how to properly use it? How do I get it to pull the message from commentnew.php? Am I going about checking for the username the wrong way? Should I be using jQuery's validation plugin somehow?
in general:
var form = $("form.commentform");
$.post(form.attr('action') , form.serialize(), function(data) {
alert("Response: " + data);
});
Try this
$("form.commentform").submit(function(e){
e.preventDefault();
$.post({
url: $(this).attr('action'),
data: $(this).serialize(),
success: function(reponse){
//here response will contain whatever you send from the server side page
}
});
}):
Look into jquery ajax function. That's what I use. http://api.jquery.com/jQuery.ajax/
