Hi:

I have the code below to display the database records in the table.  In the table, there is 'Description' field which is a text area field that can take unlimited characters.  In the table I am displaying only 255 characters and the remaining I want to display as a form, when you click on 'read more...' link.  The new page must also display other fields too.  How can this be done?

Thanks,

You will have to create a new php page to display those records. Say resid is your unique key in the table. Then you can do page.php?id=$row['resid']

On your page.php, just retrieve the information for that particular id and display the information

What is your page URL? If you are doing page.php?id=$row['resid'], then you need to get the id from URL. For that do,

$resid = $_GET['id'];

before writing the query.

My page url is http://domain.com/registration/partrecord.php, I added $resid = $_GET['id']; before the query but no change.

This is the page where you are displaying just one record from the list of records which has more than 255 characters in description, right? Here you need to tell the page which ID you are looking for, so in your main page you need to add the id to this page, so that you can get the specific resid. Show me your main page code and I will explain.

In your link for the description, do exactly what I said in my first response. And if you just want to test your new page then get and resid from your table and do page.php?id=4, this will give you the record for your resid 4. To make it a dynamic link from your main page, you will have to do page.php?id=$row['resid']

Regarding this, I have not worked on dynamic php page.

Get this book.  Very readable with excellent examples.  It will be a flash of glorious light if you have not worked much with dynamic PHP pages!

Also, learn about this function before some hacker destroys your data base.

Thanks Pranjalshah:

When I used resid = 4 it worked, but when I used partrecord.php?id=$row['resid']"] I got this error while opening the page. "Parse error: syntax error, unexpected T_STRING"

Did you use partrecord.php?id=$row['resid'] in your URL or on the main php page? please read the pages Ray has suggested. You might also want to look at the simple php get started tutorials online.

Suggested learning resources in addition to the SitePoint book:
http://php.net/manual/en/intro-whatcando.php
http://php.net/tut.php
http://extension.berkeley.edu/cat/course124.html

You might also want to make a Google search for "Learn PHP" and investigate some of the links.

Thanks again, the error is gone but it opens the URL - http://domain.com/registration/partrecord.php?id=$row[resid] and gives an error "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1"

I think we are close.  Thanks again.

Can you post the URL of the page and code and once again I suggest you to read the php mysql tutorials online. On EE you can get the ideas of how to implement but no one is going to write code for you.

First code is for the main page

Second code is for the page that opens when you click read more in the table row.

I am not sure if my post through mobile went through, but here is what you are missing

change line 28 to this,


$result = mysql_query("SELECT * FROM responses where resid='".$resid."'")  or die(mysql_error());

Thanks, but no luck in displaying particular row data on the second page.  I get a blank table.

Do some error checking. echo your query and try that query in your mysql browser and see what you get.

Without testing it and not doing any error checking how can you say this is not accurate. No one is going to write code for you here. The query I posted is correct.
