Hi,
I am trying to check for the existance of a certain value (ie $login, taken from my
first PHP page: member.php) in the "first" column of my database "mydb.
The value of "$login" is passed from member.php.
My data base "mydb" contains 1 table called emplyoees which was created as follows:
CREATE TABLE employees ( id tinyint(4) DEFAULT '0' NOT NULL AUTO_INCREMENT, first
varchar(20), last varchar(20), address varchar(255), position varchar(50), PRIMARY
KEY (id), UNIQUE id (id));
INSERT INTO employees VALUES (1,'Bob','Smith','128 Here St, Cityname','Marketing
Manager');
My code is as follows:
member.php:
<?php
// send wml headers
header("Content-type: text/vnd.wap.wml");
echo "<?xml version=\"1.0\"?>";
echo "<!DOCTYPE wml PUBLIC \"-//WAPFORUM//DTD WML 1.1//EN\""
. " \"http://www.wapforum.org/DTD/wml_1.1.xml\">";
?>
<wml>
<template>
<do type='prev' label='Back'>
<prev/>
</do>
<do type='accept' label='OK'>
<go href="http://localhost/WAP/member2.php?login=$(login)"/>
</do>
</template>
<card id='registered' title='Members'>
<p>
Please enter your First Name: <input name='login' type ='text'/>
</p>
</card>
</wml>
member2.php:
<?php
// send wml headers
header("Content-type: text/vnd.wap.wml");
echo "<?xml version=\"1.0\"?>";
echo "<!DOCTYPE wml PUBLIC \"-//WAPFORUM//DTD WML 1.1//EN\""
. " \"http://www.wapforum.org/DTD/wml_1.1.xml\">";
?>
<wml>
<card id="membercheck" title="Member Check">
<p>
<?php
$db = mysql_connect("localhost", "root");
mysql_select_db("mydb",$db);
$sql = "SELECT * FROM employees where first = '$login'";
$result = mysql_db_query ("mydb", $sql);
$myrow = mysql_fetch_array($result);
printf($myrow["first"]);
printf($myrow["last"]);
printf($myrow["address"]);
printf($myrow["position"]);
?>
</p>
</card>
</wml>
When I enter a valid "first" name ie Bob it works fine and outputs everything to the
screen.
If I enter a name that does not exist in the database it just puts up and empty WML
page.
Is there a way of checking for the existance of $login in the "first" column of my
database and if so doing somethin for example printing out "Success" other wise, if it
is not a member printing out something different?
I have tried saying
if ($result = 'Resource id #2){
print (Success);
}else{
print (Fail);
}
because if i echo out $login that is the value i get but it doesn't work.
If anyone has any alternative suggestions as an approach to this problem then I am all
ears!!
Thank you,
Kevin.
