Question 1: Printing a Document

Whenever I print an HTML page, the path of the page is printed together with the title. What should I do to avoid printing the path?

A: All you have to do is to make changes in the Headers and Footers setup of your browser. Go to File  Page setup  Headers and Footers and then make the necessary changes.

Question 2: Lostpassword.php Error

When I ran to test my script, I got the following error messages:

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/hostvad/public_html/lostpassword.php on line 19

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/hostvad/public_html/lostpassword.php on line 24

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/hostvad/public_html/lostpassword.php on line 27

The script I tested runs this way:

}

if ($pass<>'') {

Could someone enlighten me on these error messages?

A: To find out the exact problem that is causing these error messages, add the line echo Mysql_error(); before the mysql_fetch_array() function and above mysql_query().

Question 3: Checkbox Array

I had a problem when I tried to use the check box array to delete multiple records from a table. Do I have to explode the values first before I try deleting the records? Could someone give me instructions on what to do?

A: It depends really on how you use the check box array while displaying records. Nevertheless, you can look at the page where you declare the check box name as array by using the following script:

checkbox name=test[] value=>

When you submit the page, you can find the checkbox array through the POST method using the script below"

foreach($test as $tempVal)

{

//Here u can perform the update or delete operation

}

?>

You will find this very easy to implement.

Question 4: Redirecting PHP Results to Calling HTML Page

I have an HTML page with hyperlinks on it with the name index.html. The page layout is shown below and the links are in TABLE 2. The Xs denote the shape layout of the table on the web page.

TABLE 1

xxxx

xxxx

xxxx

xxxx TABLE 2:

xxxx - link1

xxxx - link2

xxxx - getlist.php

TABLE 3

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xx

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xx

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xx

The hyperlinks run/trigger PHP scripts. For example: getlist.php. The PHP script queries a MySQL database. The results are produced and then viewed on a new web page.

I want to imbed the results on the calling HTML page, i.e., index.html and I want them to appear in a specific location on that page. The specific location is in the same Table 2 but below the listing of the hyperlinks. For example:

TABLE 2

Link 1

Link 2

getlist.php

I want the results to appear in the following links in TABLE 2:

Link 1

Link 2

getlist.php

RRRRRRRRRRReeeeeeeSSSSSSuuuuuLLLttttSSS.

RRRRRRRRRRReeeeeeeSSSSSSuuuuuLLLttttSSS.

RRRRRRRRRRReeeeeeeSSSSSSuuuuuLLLttttSSS.

Below is my PHP code. I got the results to appear on the calling HTML page when I put the PHP INCLUDE code in the script but I cannot anchor them to the specific location.

index.html); ?>

$db_name = firstdb;

$table_name = table1;

$connection = @mysql_connect(servername, username, password)

or die(mysql_error());

$db = @mysql_select_db($db_name, $connection) or

die(mysql_error());

$sql = SELECT * FROM $table_name where city = 'washington' ORDER BY Name;

$result = @mysql_query($sql, $connection) or die(mysql_error());

while ($row = mysql_fetch_array($result)){

$Name = $row['Name'];

$Description1 = $row['Description1'];

$Address = $row['Address'];

$Telephone = $row['Telephone'];

$Email = $row['Email'];

$WebSite = $row['WebSite'];

$display_block .= "

$Name ($Address)

$Telephone ($Email) ( $WebSite )

";

}

?>

ResultsList

$display_block; ?>

Right now, the results appears as follows:

TABLE 3

xxxxxxxxxxxxxxxxxxxxxxxxxxx

xxxxxxxxxxxxxxxxxxxxxxxxxxx

xxxxxxxxxxxxxxxxxxxxxxxxxxx

Here is where the results now appear:

RRRRRRReeeeeeeeSSSSSSSSuuuuuuuuuLLLLLLLttttttttttS SSSSS

RRRRRRReeeeeeeeSSSSSSSSuuuuuuuuuLLLLLLLttttttttttS SSSSS

RRRRRRReeeeeeeeSSSSSSSSuuuuuuuuuLLLLLLLttttttttttS SSSSS

How do I anchor the results into TABLE 2?

A: Assuming that you do not have problems in running PHP code within an .html extension, you could try to move up the PHP code and then add the line:

$display_block; ?>

In the line below Table 2, remove the $display_block
