Can anyone offer any insight as to why i'm getting these notices...?
any help would be greatly appreciated.
You can't reference keys from an array that doesn't have them, and that's what you're trying to do from the $_POST array, since the request didn't have those values posted.
To get rid of the notices, change all of your declarations where you pull values from $_POST directly from:
$Surname = $_POST['surname'];
To:
$Surname = isset( $_POST['surname']) ? $_POST['surname'] : ""; // Some default value
Also, in your code you're inserting the same query twice it looks like. And, VDP brings up a good point, you don't want to insert empty rows, so to fix that, you can wrap the whole logic for inserting with an if statement, check if the $_POST is empty, or check if every variable has a valid value before inserting.
Edit: OK, a more thorough explanation.
When you try to access keys from an array that the array does not have, you get this notice. So, your $_POST array is likely empty, because when you accessed the page, you didn't submit a POST request to it, or if you did, you didn't send the variables it's expecting.
So $_POST looks like:
$_POST = array( );
And you're trying to do:
$Surname = $_POST['surname']; // DOESN'T EXIST!
Clearly, you can't do that. So, instead of directly grabbing things from $_POST, you check if that key actually exists in the $_POST array:
$Surname = isset( $_POST['surname']) ? $_POST['surname'] : "";
However, this is just shorthand for:
if( isset( $_POST['surname'])) {
$Surname = $_POST['surname'];
} else {
$Surname = "";
}
It's called the ternary operator, and you can look it up on the PHP documentation to read more about it.
Instead of
$Surname = $_POST['surname'];
Do
if(isset($_POST['surname']))
{
$Surname = $_POST['surname'];
}
Or
$Surname = (isset($_POST['surname'])) ? $_POST['surname'] : $some_string; /* or something */
You could also just use extract() for localising all those post variables.
If you are COMPLETELY SURE that those notices won't screw your application and want a quick fix use
error_reporting(0);
or use #$variable;
I repeat, this is not really a solution but a temporal quick fix.
For really fixing it you should always check for the existence of the variables.
echo $myvariable; // will output notice
$myvariable = null;
echo $myvariable; // will output nothing but nor the notice
A good way is to use :
if(isset($_POST['myvariable'])){
$myvariable = $_POST['myvariable'];
} else {
$myvariable = null;
}

I'm trying to get a value of a form in Wordpress to PHP. The form is like this and it is displaying fine in the preview:
<form action=".../name.php" method="get">
<input type="checkbox" name="form_ques_4" value=0 />
<input type="checkbox" name="form_ques_4" value=1 />
<input type="checkbox" name="form_ques_4" value=2 />
<input type="submit" name="formSubmit" value="submit" />
</form>
If the user selected option 2, the value is 1 and this will later be used as the input in a MySQL database. As I have read in other posts, I should get value with the php line.
$a = $_GET["form_ques_4"];
I have tested some other simple outputs for the .php and there is no problem with the "form action" of the wordpress. I also tried using single and double quotes for the "GET" with no result.
Try to change the names of your checkboxes, if you want a user multiple choice:
<form action=".../name.php" method="get">
<input type="checkbox" name="form_ques_1" value="0" />
<input type="checkbox" name="form_ques_2" value="1" />
<input type="checkbox" name="form_ques_3" value="2" />
<input type="submit" name="formSubmit" value="submit" />
</form>
otherwise, if you want the user makes only one choice use type="radio"
<form action=".../name.php" method="get">
<input type="radio" name="form_ques_4" value="0" />
<input type="radio" name="form_ques_4" value="1" />
<input type="radio" name="form_ques_4" value="2" />
<input type="submit" name="formSubmit" value="submit" />
</form>
EDIT
yes, as AZinkey says, you can also use
<form action=".../name.php" method="get">
<input type="checkbox" name="form_ques[]" value="0" />
<input type="checkbox" name="form_ques[]" value="1" />
<input type="checkbox" name="form_ques[]" value="2" />
<input type="submit" name="formSubmit" value="submit" />
</form>
then get the results in php
$checked = $_GET['form_ques'];
for($i=0; $i < count($checked); $i++){
echo $checked[$i] . "<br/>";
}
Quote your value attribute like value="0" and update name to "form_ques_4[]"
<input type="checkbox" name="form_ques_4[]" value="0" />
i have a html form that has a more then 30 checkboxes. checkboxes are used to select for different service.
I want to store those all value in 1 Database field seperated by , those could be numeric or string. Code for inserting checkbox values is as follows:
<form method="post" action="posted.php">
Option 1: <input type="checkbox" name="type" value="1" /><br />
Option 2: <input type="checkbox" name="type" value="2" /><br />
Option 3: <input type="checkbox" name="type" value="3" /><br />
Option 4: <input type="checkbox" name="type" value="4" /><br />
Option 5: <input type="checkbox" name="type" value="5" /><br />
Option 6: <input type="checkbox" name="type" value="6" /><br />
Option 7: <input type="checkbox" name="type" value="7" /><br />
Option 8: <input type="checkbox" name="type" value="8" /><br />
Option 9: <input type="checkbox" name="type" value="9"/><br />
<input type="submit" value="Submit" />
</form>
After successful submission off course i need to fetch those data in the corespondent check box while update.
Please response me as soon as possible with complete PHP code.
You can use JSON. From this:
Option 1: <input type="checkbox" name="myval[option_name1]" /><br />
Option N: <input type="checkbox" name="myval[option_nameN]" /><br />
Store:
$model->field = json_encode($_POST['myval']);
Or comma-seporated (if you really want):
$model->field = implode(",", $_POST['myval']);

$_POST = array( );
is wrong, remove this line.
$_POST is an array() you do not have to declare this.
according the screed shot in comment you are checking the structure ... click on the Browse tab than you will see the content
also try
mysql_query($query) or die(mysql_error());
to see the error in query
Warning : your code is vulnerable to SQL Injunction
also MySql_* function are deprecated use pdo or mysqli
Things that could solve your problem:
mysql_query($query) or die(mysql_error() . ' ' . $query);
don't clear out the post array
don't suppress the database connection or at least put the error in the die
Things you should probably fix, but probably isn't your problem:
$sql injection by putting the variables in the sql without escaping
them Using mysql instead of mysqli Validating the data, doing
controller stuff after the html started using radio buttons like
checkboxes not using an absolute path for your url
don't use root as the username to you db and have no password
no html should be in between the head and body.
Also I'm not sure you can have "" as the auto increment id. I would put Null there instead. Even better I'd explicitly put the columns you want to add to the table. You will have a of headaches later if you don't....say you have that same insert into a 1000 places...well you add a column and now you have to update a 1000 places.
Also I would echo out the sql statement you made and try and run it via command prompt or phpmyadmin.
I have multiple checkboxes on my form:
<input type="checkbox" name="animal" value="Cat" />
<input type="checkbox" name="animal" value="Dog" />
<input type="checkbox" name="animal" value="Bear" />
If I check all three and hit submit, with the following code in the PHP script:
if(isset($_POST['submit']) {
echo $_POST['animal'];
}
I get "Bear", i.e. the last chosen checkbox value even though I picked all three. How to get all 3?
See the changes I have made in the name:
<input type="checkbox" name="animal[]" value="Cat" />
<input type="checkbox" name="animal[]" value="Dog" />
<input type="checkbox" name="animal[]" value="Bear" />
you have to set it up as array.
print_r($_POST['animal']);
<input type="checkbox" name="animal[]" value="Cat" />
<input type="checkbox" name="animal[]" value="Dog" />
<input type="checkbox" name="animal[]" value="Bear" />
If I check all three and hit submit, with the following code in the PHP script:
if(isset($_POST['animal'])){
foreach($_POST['animal'] as $animal){
echo $animal;
}
}
use square brackets following the field name
<input type="checkbox" name="animal[]" value="Cat" />
<input type="checkbox" name="animal[]" value="Dog" />
<input type="checkbox" name="animal[]" value="Bear" />
On the PHP side, you can treat it like any other array.
here is the code:
<ul>
<li><a id="various3" href="index2.html">Opera</a></li>
<li><a id="various3" href="index2.html">Chrome</a></li>
</ul>
it is available in index2.html

when i run index.html file. it has two link Opera and chrome. on clicking both it goes to index2.html. that is fine..
now i need to dynamically load form. the index2.html contains 14 question. when opera in clicked that 1,3,4,5,6,7 questions to be loaded and when chrome is clicked the remaining quesitons should be loaded. instead of making two html file to do this. is there any way to load the form based on selected option using php????
change your links to
<li><a id="various3" href="index2.html?browser=opera">Opera</a></li>
<li><a id="various3" href="index2.html?browser=chrome">Chrome</a></li>
then in index2 you can see the browser selected in the $_GET global
$_GET['browser']
then you can go
if ($_GET['browser']=='opera'){
//whatever
}
