[jiameow]

I was wondering how can you solve this type of error "undefined index? please answer 

[jazzman1]

When you defined it

[jiameow]

how do you do that? I can't understand it :x 

[requinix]

Here's a how-to for using a great resource to solve this kind of problem.

[jiameow]

we can't seem to make it work

[Maq]

POST YOUR CODE.

[jiameow]

<?php
include_once "add2.php";
connect();
?>

<?php
if (!isset($_POST['submit'])){

echo "<form method=\"post\" action=\"admin-addservice.php\" name=\"Registration Form\">";
echo "<br/>";
echo 'Name of Service: ' . '<br/>' . '<input type=\"text\" name=\"service\" style="width:400px;"/>' . '<br/>' . '<br/>';
echo "Description: " . "<br/>";
echo '<textarea cols="80" rows="10" name=\"description\" maxlength=\"1000\" style=\"overflow: hidden;\">';
echo '</textarea>' . '<br/>' . '<br/>';
echo "Price: " . '<br/>';
echo "<input type=\"text\" name=\"price\" style='width:200px;'/>" . '<br/>';
echo "<input type=\"submit\" name=\"submit\" value=\"Finish Registration!\" />";
echo "</form>";

?>
<?php

}else {

$service = protect($_POST['service']);
$description = protect($_POST['description']);
$price = protect($_POST['price']);

$errors = array();

[jazzman1]

Where do you declare the protect function in that script?

[jiameow]

in our else statement

[jazzman1]

in our else statement

No, that's wrong!

[jiameow]

where should we put it then?

[jazzman1]

You need to create that function before to use it.

[jiameow]

here is our full code

 

 

<?php
include_once "add2.php";
connect();

mysql_connect("localhost","root","");
mysql_select_db("patient");

if (!isset($_POST['submit'])){
echo "<form method=\"post\" action=\"admin-addservice.php\" name=\"Registration Form\">";
echo "<br/>";
echo 'Name of Service: ' . '<br/>' . '<input type=\"text\" name=\"services\" style="width:400px;"/>' . '<br/>' . '<br/>';
echo "Description: " . "<br/>";
//echo '<textarea cols="80" rows="10" name=\"description\" maxlength=\"1000\" style=\"overflow: hidden;\">';
//echo '</textarea>' . '<br/>' . '<br/>';
echo "<input type=\"text\" name=\"\">";
echo "Price: " . '<br/>';
echo "<input type=\"text\" name=\"price\" style='width:200px;'/>" . '<br/>';
echo "<input type=\"submit\" name=\"submit\" value=\"Finish Registration!\" />";
echo "</form>";

}else {

$service = protect($_POST['services']);
$description = protect($_POST['description']);
$price = protect($_POST['price']);

$errors = array();
if(!$service) {
$errors[] = "Invalid Name of Service!";
}
if(!$description) {
$errors[] = "Invalid Description!";
}
if(!$price) {
$errors[] = "Invalid Price!";
}
if (count($errors) > 0) {
foreach($errors AS $error) {
echo ("<SCRIPT LANGUAGE='JavaScript'>
window.alert('$error')
window.location.href='admin-addservice.php'
</SCRIPT>");
}
}
else {
$sql = "INSERT INTO services(services , description , price) VALUES('$_POST[services]' , '$_POST[description]' , '$_POST[price]')";
$res = mysql_query($sql) or die (mysql_error());
?>
<script type=text/javascript>
function show_alert() {
var msg = "Successfully Saved!";
alert(msg);
}
</script>
<?php

echo "<br/>";
echo '<script type="text/javascript"> show_alert(); </script>';
echo "<br/>";
echo "<br/>";
echo "<br/>";

}
}

?>

[jiameow]

we dont have any knowledge about php so far :/

[jazzman1]

we dont have any knowledge about php so far :/

 

Me too.

 

What do you have in the add2.php file?

[jiameow]

it holds the protect function and connection

[jiameow]

Me too.

 

What do you have in the add2.php file?

<?php

 

function protect($string)

{

$string = mysql_real_escape_string($string);

$string = strip_tags($string);

$string = addslashes($string);

 

return $string;

 

}

function connect () {

$con = mysql_connect("localhost", "root",'') or die(mysql_error());

$db = mysql_select_db("patient", $con);

 

}

 

?>

[jazzman1]

Ok, then!

 

Put the error_reporting(-1) to the top of the file and tell us what error(s) do you get?

 

Copy/Paste my script!

 

Ops....there is no return $con in connect() function inside the add2.php file!

 

 

 

 
function connect () {
$con = mysql_connect("localhost", "root",'') or die(mysql_error());
$db = mysql_select_db("patient", $con);
return $con;
}

 

<?php
error_reporting(-1);
include_once "add2.php";
connect();

if (!isset($_POST['submit'])){
echo "<form method=\"post\" action=\"admin-addservice.php\" name=\"Registration Form\">";
echo "<br/>";
echo 'Name of Service: ' . '<br/>' . '<input type=\"text\" name=\"services\" style="width:400px;"/>' . '<br/>' . '<br/>';
echo "Description: " . "<br/>";
//echo '<textarea cols="80" rows="10" name=\"description\" maxlength=\"1000\" style=\"overflow: hidden;\">';
//echo '</textarea>' . '<br/>' . '<br/>';
echo "<input type=\"text\" name=\"\">";
echo "Price: " . '<br/>';
echo "<input type=\"text\" name=\"price\" style='width:200px;'/>" . '<br/>';
echo "<input type=\"submit\" name=\"submit\" value=\"Finish Registration!\" />";
echo "</form>";

}else {

$service = protect($_POST['services']);
$description = protect($_POST['description']);
$price = protect($_POST['price']);

$errors = array();
if(!$service) {
$errors[] = "Invalid Name of Service!";
}
if(!$description) {
$errors[] = "Invalid Description!";
}
if(!$price) {
$errors[] = "Invalid Price!";
}
if (count($errors) > 0) {
foreach($errors AS $error) {
echo ("<SCRIPT LANGUAGE='JavaScript'>
window.alert('$error')
window.location.href='admin-addservice.php'
</SCRIPT>");
}
}
else {
$sql = "INSERT INTO services(services , description , price) VALUES('$_POST[services]' , '$_POST[description]' , '$_POST[price]')";
$res = mysql_query($sql) or die (mysql_error());
?>
<script type="text/javascript">
function show_alert() {
var msg = "Successfully Saved!";
alert(msg);
}
</script>
<?php

echo "<br/>";
echo '<script type="text/javascript"> show_alert(); </script>';
echo "<br/>";
echo "<br/>";
echo "<br/>";

}
}

"Undefined index: service D:\xampp\htdocs\def\admin-addservice.php on line 93

[jazzman1]

Which is the line 93?

Edited March 15, 2013 by jazzman1

[jiameow]

Which is the line 93?

$service = protect($_POST['services']);

[jazzman1]

There is only 63 rows inside that particular file

 

Are you sure that that file is called - admin-addservice.php?

[jiameow]

yes

[jazzman1]

And.... you posted the entire script?

[jiameow]

yup the entire php script
