$_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.

Saving Radio Button Inputs into Array
I am working on a custom survey that is dynamically populated with database information and needs to be saved as an array. I can make everything work as it should except I would like to use a star rating system for many of the answers and it seems radio buttons won't work like this:
<input type="radio" name="surveyRating[]" value="1" />
<input type="radio" name="surveyRating[]" value="2" />
<input type="radio" name="surveyRating[]" value="3" />
<input type="radio" name="surveyRating[]" value="4" />
<input type="radio" name="surveyRating[]" value="5" />
Because there are multiple instances of this same code. This will be saved into an array so surveyRating will be used over and over again. If I click a radio button in one group, it changes to a radio in another group.
I have read I can possibly do this with checkboxes instead. Is that the best alternative? Or is there another option I should be looking at? I want the final product to be star ratings 1-5. Not sure if I can do that with checkboxes.
EDIT
Ok so using name="surveyRating[1]" is helping as far as the radio buttons not conflicting on the client side. However, it is not saving correctly the way I have my php set up now. Here is how it is saved currently. What do I need to change to make the [1] work appropriately. Currently it is only saving the last iteration.
$new = array();
$ratings = $_POST['surveyRating'];
$count = count( $ratings );
for ( $i = 0; $i < $count; $i++ ) {
if ( $ratings[$i] != '' ) {
$new[$i]['surveyRating'] = stripslashes( strip_tags( $ratings[$i] ) );
}
}
EDIT 2
So to demonstrate how I accomplished this using the answer below, I had to add [0] as the first iteration in the loop. I was using $items = 0; $items++ to dynamically add a number to each loop.
To make it start at 0, I set $items = -1 that way the first iteration is 0 instead of 1. Hope that makes sense.
Yep, it does because you have the name with []. That's for array. Remove it and you will get it without array: <input type="radio" name="surveyRating" value="1" /> <input type="radio" name="surveyRating" value="2" /> <input type="radio" name="surveyRating" value="3" /> <input type="radio" name="surveyRating" value="4" /> <input type="radio" name="surveyRating" value="5" /> For radio buttons with several groups, you have to do something like this: <!-- Group 1 --> <input type="radio" name="surveyRating[1]" value="1" /> <input type="radio" name="surveyRating[1]" value="2" /> <input type="radio" name="surveyRating[1]" value="3" /> <input type="radio" name="surveyRating[1]" value="4" /> <input type="radio" name="surveyRating[1]" value="5" /> <!-- Group 2 --> <input type="radio" name="surveyRating[2]" value="1" /> <input type="radio" name="surveyRating[2]" value="2" /> <input type="radio" name="surveyRating[2]" value="3" /> <input type="radio" name="surveyRating[2]" value="4" /> <input type="radio" name="surveyRating[2]" value="5" />
Get variable on Wordpress to PHP
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" />
PHP How to keep radio button state to the next page
I made a form with radio buttons. How can I preserve it's state after a user picked a choice? Then same form will show again in the next page and the radio button that the user picked is enabled. //page1.html <form method="post" action="page2.html"> <p> <input type="radio" name="q1" value="A" /> A. <br /> <input type="radio" name="q1" value="B" /> B. <br /> <input type="radio" name="q1" value="C" /> C. <br /> <input type="radio" name="q1" value="D" /> D. <p> <input type="submit" name="action" value="Enter" /> </p> </form>
To get the value of q1 on the next page, you would use $_POST['q1']. You can verify that the element has been posted, and the value matches the specific radio button by using if(isset($_POST['q1'])) && $_POST['q1'] == VALUE. So your form code would look like - <input type="radio" name="q1" value="A" <?php if(isset($_POST['q1']) && ($_POST['q1'] == 'A')) echo 'checked="checked" ';?>/> A. <br /> <input type="radio" name="q1" value="B" <?php if(isset($_POST['q1']) && ($_POST['q1'] == 'B')) echo 'checked="checked" ';?>/> B. <br /> <input type="radio" name="q1" value="C" <?php if(isset($_POST['q1']) && ($_POST['q1'] == 'C')) echo 'checked="checked" ';?>/> C. <br /> <input type="radio" name="q1" value="D" <?php if(isset($_POST['q1']) && ($_POST['q1'] == 'D')) echo 'checked="checked" ';?>/>

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;
}

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
}
