Change the "ORDER BY" with forms

[triphis]

I was wondering how I can reorder the MySQL query \"order by\" with the use of forms. I have no clue.

 

My friend owns this site, but because she knows ASP, rather than PHP, she was unable to help me.

See all the buttons? By clicking on them, the list order is changed.

you\'d want to pass a variable to the page and have that variable tell what query to run. Something like

 

[php:1:74ec0ffbbe]<?php

if ($_REQUEST[submitted] == \"true\")

{

 

$sort = $_POST[\'sort\'];

 

if ($sort == \"name\")

{

$query = mysql_query(\"select user_id, user_name, user_address, user_type from table ORDER BY user_name\");

} elseif ($sort == \"address\") {

$query = mysql_query(\"select user_id, user_name, user_address, user_type from table ORDER BY user_address\");

} elseif ($sort == \"type\") {

$query = mysql_query(\"select user_id, user_name, user_address, user_type from table ORDER BY user_type\");

} else {

$query = mysql_query(\"select user_id, user_name, user_address, user_type from table ORDER BY user_id\");

}

}

?>

<FORM ACTION=\"<?= $_SERVER[\"PHP_SELF\"] ?>\" METHOD=\"post\">

 

<SELECT NAME=\"sort\">

<OPTION SELECTED VALUE=\"name\">User Name

<OPTION VALUE=\"address\">User Address

<OPTION VALUE=\"type\">User Type

</SELECT>

</FORM>

[/php:1:74ec0ffbbe]

 

That\'s how I\'d do it anyway

Hey, if I wanted to shorten this:

 

[php:1:d805344b15]<?php

if ($sort == \"name\")

{

$query = mysql_query(\"select user_id, user_name, user_address, user_type from table ORDER BY user_name\");

} elseif ($sort == \"address\") {

$query = mysql_query(\"select user_id, user_name, user_address, user_type from table ORDER BY user_address\");

} elseif ($sort == \"type\") {

$query = mysql_query(\"select user_id, user_name, user_address, user_type from table ORDER BY user_type\");

} else {

$query = mysql_query(\"select user_id, user_name, user_address, user_type from table ORDER BY user_id\");

}

?>[/php:1:d805344b15]

 

I could go like this right? :

 

[php:1:d805344b15]

$query = mysql_query(\"select user_id, user_name, user_address, user_type from table \");

if ($sort == \"name\")

{

$query .= ORDER BY user_name;

} elseif ($sort == \"address\") {

$query .= ORDER BY user_address;

} elseif ($sort == \"type\") {

$query .= ORDER BY user_type;

} else {

$query .= ORDER BY user_id\");

}

[/php:1:d805344b15]

 

I don\'t know the correct use of \" .= \" but I know it adds to a previous variable.
