Get results from a Query, into a hyperlink
I was wondering, when i query my DB, and it kicks out results.
I wanted first to check and not duplicated any values that are the same.
So for each of my records, it will have a partnumber,descripton, and a PO attached to it.
Now alot of my parts will be on the same po, i just wanted it to look through the MBlock_PO column, and only pick out uniq PO numbers, and not display the same PO 4 or 5 times.
Also how do i make them hyperlinks, that will make the lower portion of my form visable, with update potions of the po..
i hope this makes sense, or if easier i can make it go to a new page, where it will show all the parts on that po..
Re: Get results from a Query, into a hyperlink
you can change your query to something like this:
PHP Code:
SELECT DISTINCT partnumber, otherfield, otherfield2 FROM tablename WHERE something='something else'
This will look for only unique results where instances of partnumber, otherfield, and otherfield2 are not duplicated.
if you want to make results into links, then just make a link in your while loop..
PHP Code:
while($row = mysql_fetch_array($blah)){
echo '<a href="./somepage.php?partnumber=' . $row['partnumber'] . '">' . $row['sometext'] . '</a><br />\n';
}
Re: Get results from a Query, into a hyperlink
ok this is what i have but it throws errors.
Open Purchase Orders:
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in C:\Inetpub\jf1\php\testing2.php on line 81
Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in C:\Inetpub\jf1\php\testing2.php on line 83
PHP Code:
<?php
$query5 = "SELECT DISTINCT MBlock_PO From dss ";
$result5 = @mysql_query ($query5);
$count5 = mysql_num_rows($result5); //number of results
while($row = mysql_fetch_array($result5, MYSQL_ASSOC)){
echo '<a href="./somepage.php?partnumber=' . $row['MBlock_PO'] . '">' . '</a><br />\n';
}
?>
Re: Get results from a Query, into a hyperlink
uhh.. what you have won't even print anything, you have to have text in between your <a> and </a> tags for it to even show up on the page.
as for the errors, are you connected to a mysql server and did you select the database..? other than that, I have no idea what's wrong with your stuff. the code is fine, so it has to do with your query.
I just went and made a test table and tried using similar code, which resulted in the same error you were getting.. however, this error was because the table I had was named "table," which is a reserved word, and I was using "SELECT DISTINCT * FROM table." If you use reserved words for field/table names, you should enclose them in (`)'s, so that MySQL will recognize them.
The code I used is as follows:
PHP Code:
<?
mysql_pconnect(host, user, pass);
mysql_select_db("testing");
$request = "SELECT DISTINCT test FROM dss";
$query = mysql_query($request);
$num = mysql_num_rows($query);
echo 'showing ' . $num . ' records<br />';
$i = 0;
while($data = mysql_fetch_array($query)){
$i++;
echo $i . '. ' . $data['test'] . '<br />';
}
?>
My final test table was named "dss" with one field named "test" and had 7 entries. All of them were unique, except two, so when using this script it only displayed 5:
HTML Code:
showing 5 records
1. 234
2. sfsdfs
3. 452345
4. 2423
5. 1
Not sure how your database is set up, but it seems to me that you're either leaving something important out of the code, or you're using reserved words in your queries and not properly quoting them.

Re: Get results from a Query, into a hyperlink
ok i think i got it, this is what i used...
Now how do i make them hyper links?
i wanted to be able to click on the one of the PO and it goes to another screen where it will list all the items from that po, and i can edit any line on that po.
PHP Code:
<?
require_once ('mysql_connect.php');
$request5 = "SELECT DISTINCT MBlock_Returned_PO FROM dss";
$query5 = mysql_query($request5);
$num5 = mysql_num_rows($query5);
//echo 'showing ' . $num5 . ' records<br />';
$i = 0;
while($data = mysql_fetch_array($query5)){
//$i++;
echo '<li />' . $data['MBlock_Returned_PO'] . '<br />';
}
?>
Re: Get results from a Query, into a hyperlink
ok just for everyone, here is my php that fixed it
PHP Code:
<?
require_once ('mysql_connect.php');
$request5 = "SELECT DISTINCT MBlock_Returned_PO,MBlock_PO_Completed FROM dss";
$query5 = mysql_query($request5);
$num5 = mysql_num_rows($query5);
//echo 'showing ' . $num5 . ' records<br />';
$i = 0;
while($data = mysql_fetch_array($query5)){
$i++;
echo '<li /> <a href="./somepage.php?partnumber=' . $i . '">' . $data['MBlock_Returned_PO'] . '</a><br />';
// echo '<li />' . $data['MBlock_Returned_PO'] . '<br />';
}
?>
