I am a beginner with php. I am using twitter-bootstrap to create a website. I would like to store the data submitted from a website dropdown menu into a MySQL database named datawebcollectiondb . I am able to store information in the db when the user submits input from an open text field, but not from a drop down menu. The database fills with 0s in all fields when the dropdown menu is submitted.
First the open text field that did work:
HTML file:
<html>
<body>
<form action="insert.php" method="post">
Number Please: <input type="text" name="directionp">
Another Number: <input type="text" name="timep">
Third Number: <input type="text" name="locationp">
Fourth Number: <input type="text" name="searchtimep">
<input type="submit">
</form>
</body>
</html>
PHP file that worked:
<?php
$con = mysql_connect("host", "username", "password");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("timeforparkingdb", $con);
$sql="INSERT INTO datawebcollection (directionp, timeofdayp, locationp, searchtimep)
VALUES
('$_POST[directionp]','$_POST[timep]','$_POST[locationp]','$_POST[searchtimep]')";
if (!mysql_query($sql,$con))
{
die('Error: ' . mysql_error());
}
echo "1 more record added =) ";
mysql_close($con);
?>
HTML file that did NOT work in tandem with above php file, other than populating db with 0s:
<html>
<form action="insert.php" method="post">

<select name="directionp">
<option value="1">Coming</option>

Original MySQL Database Structure:
Field Type Collation Attributes Null Default Extra Action
unique_entry_id int(11) No
dayp int(2) No
monthp int(2) No
yearp int(4) No
directionp int(1) No
timeofdayp int(2) No
locationp int(2) No
searchtimep int(2) No
What I see inside my database so far:
unique_entry_id dayp monthp yearp directionp timeofdayp locationp searchtimep
0 6 6 6 0 0 0 0
0 7 7 7 0 0 0 0
0 8 24 2345 0 0 0 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0
The rows with values other than 0 are from when I ran the original code, and the rows with only 0s are from the dropdown form. How can I get the correct correlated option value to be the value stored into the database? I would have thought that the value assigned to the option, i.e. <option value="1">Zone One</option> <option value="2">Zone Two</option>, would have been the value submitted to the db.
What I saw on my chrome developer console under form data:
direction=2&time=5&location=5&searchtime=25
and still the database recorded all 0s.
Corrected MySQL Database Structure:
Present Corrected Database Structure:

locationp int(2) No
searchtimep int(2) No
In order to pass integers and not text to the mySQL db from my php code I’ve removed the single quotes:
<?php
$con = mysql_connect("", "", "");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("timeforparkingdb", $con);
$sql="INSERT INTO datawebcollection (directionp, timeofdayp, locationp, searchtimep)
VALUES
($_POST[directionp],$_POST[timep],$_POST[locationp],$_POST[searchtimep])";
if (!mysql_query($sql,$con))
{
die('Error: ' . mysql_error());
}
echo "Thank you for your submission! 1 more record added =) ";
mysql_close($con);
?>
First step in order to avoid SQL injection I have modified my HTML to:
<form action="insert.php" id="timeforparking" method="post">
<input type="submit">
</form>
and:
DIRECTION:
<select form = "timeforparking" id="directionp">
<option value="1">Parking In Manhattan</option>
<option value="2">Leaving Manhattan</option>
</select>
TIME:
<select form = "timeforparking" id="timep">
<option value="0">12:00am - 1:00am</option>
<option value="1">1:00am - 2:00am</option>
<option value="2">2:00am - 3:00am</option>
<option value="3">3:00am - 4:00am</option>
<option value="4">4:00am - 5:00am</option>
<option value="5">5:00am - 6:00am</option>
<option value="6">6:00am - 7:00am</option>

And I will have to do something to the php to avoid injection, and I do not undertand what I need to do for this yet, and I am presently researching this at http://php.net/manual/en/pdo.prepared-statements.php, and trying to apply the following to my case:
This example performs an INSERT query by substituting a name and a value for the named placeholders.
<?php
$stmt = $dbh->prepare("INSERT INTO REGISTRY (name, value) VALUES (:name, :value)");
$stmt->bindParam(':name', $name);
$stmt->bindParam(':value', $value);
// insert one row
$name = 'one';
$value = 1;
$stmt->execute();
// insert another row with different values
$name = 'two';
$value = 2;
$stmt->execute();
?>
It may be that some of my values are empty. Next I hope to check the POST parameters and print them out in the php code via Print out post values , specifically:
<?php
// loop through every form field
while( list( $field, $value ) = each( $_POST )) {
// display values
if( is_array( $value )) {
// if checkbox (or other multiple value fields)
while( list( $arrayField, $arrayValue ) = each( $value )) {
echo "<p>" . $arrayValue . "</p>\n";
}
} else {
echo "<p>" . $value . "</p>\n";
}
}
?>
output after submit:
blank white screen
Does this mean that I am trying to pass empty values to my db? And I am no longer receiving all 0s in my database as I know have a SQL error (or is that because I am passing blank values ,i.e. $_POST[locationp] and $_POST[searchtimep] are empty? is that the right conclusion? if so, why is it doing that?) with the updated PHP without single quotes; With the latest PHP [as seen above without single quotes, so it doesn’t send as text] and the HTML above that now uses an ID tag for the form, I recieve:
"Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ',,)' at line 3"
when I ty to submit from the webpage. And it follows that Chrome is not displaying anything regarding form values, only “Request Headers” and “Response Headers” are listed.
My original question/post is still: storing values in a MySQL db from a drop down menu?
A related question that I was unable to glean a solution from: Inserting Data from dropdown into database with PHP
Your PHP script is expecting form variables named e.g. directionp, however the post data from Chrome is displaying direction (with no p on the end.)
Are you sure your form elements are named correctly in your HTML? It would appear so from your listing, however your form data looks different.
