How could I determine the data from clicking a link? - php

Question

I am a newbie in php and working on something something and I can't figure out how will it work. I have a query like this which will display specific rows from the database:
<?php
include ('test/tru/conek.php');
$result=mysql_query("SELECT * FROM post_jobs WHERE job_category='Administration'");
while($row=mysql_fetch_array($result)){
?>
<tr >
<th style="font-weight:normal"><input type="text" name="name" value="<?php $name=$row['company_name']; echo $name ; ?>" readonly="readonly" /></th>
<th style="font-weight:normal"><?php echo $row['job_responsibilities']; ?></th>
<th style="font-weight:normal" id="industry"><?php echo $row['industry']; ?></th>
<th style="font-weight:normal" id="date"><?php echo $row['date']; ?></th>
<th style="font-weight:normal" id="loc"><?php echo $row['location']; ?></th>
</tr>
</table>
<?php } ?>
My question is, how could I display or determine the information on a specific row from clicking the link and then displaying it?

Answer 1

It seems like you want differentiate between the rows after printing them onto screen. The most common way of doing this is by using an id number for each row. You add an 'id' row which is auto incrementing and primary into your mysql table. You would then add it to the link in your html:
<th style="font-weight:normal">
<a href="#" onclick="ss(<?php echo htmlspecialchars($row['id'], ENT_QUOTES, 'UTF-8'); ?>)" name="res">
<?php echo htmlspecialchars($row['job_responsibilities'], ENT_QUOTES, 'UTF-8'); ?>
</a>
</th>
You would then do something with that id number in Javascript in your ss() function. If you infact don't want to use Javascript at all, then you should write your link tag as:
<th style="font-weight:normal">
<a href="somewhere.php?id=<?php echo htmlspecialchars($row['id'], ENT_QUOTES, 'UTF-8'); ?>" name="res">
<?php echo htmlspecialchars($row['job_responsibilities'], ENT_QUOTES, 'UTF-8'); ?>
</a>
</th>
I think that's what you're looking for.
Edit: How silly of me, I also forgot to mention that you should never print user-supplied data in your html without first escaping it. This is to prevent Cross Site Scripting (XSS) which is a common yet very serious vulnerability in web pages. I've edited my code accordingly. You should replace the 'UTF-8' with the correct encoding of your data. This is the reason you should also explicitly state the encoding: http://shiflett.org/blog/2007/may/character-encoding-and-xss
