My file is a learning exercise.  It has a simple form, and it uses the inserted data and is supposed to add the data to my simple database.  It seems to be collecting the data (at least, if I echo the gathered data it shows properly) - so I don't know why the data is not uploaded.  I understand it could be several things - but I don't know where to begin checking.  I'm not getting any errors.

 

Here is my file:  (I removed the actual user and password and the database name substituted placeholders here)     

 

more info:  the table has the fields in the form plus one more -  ID (set to autoincrement)      If nothing is wrong here, where should I begin to look??

One good debugging trick is to go right below the query, copy whatever is in the query, and then die with it.

 

So, right where you have:

 

$result = mysql_query($query);

 

add below it:

 

echo mysql_error();

die($query);

 

Three things are learned from this.

 

1) You know the query is getting called.

2) You know the exact values going into it.

3) You know if there are any mysql errors.

 

If that still doesn't work, copy the query and try to put it in PHP myadmin, and see if it acctually does something in mysql.

I think that you need the field names in the query:

$query="INSERT INTO 'table' VALUES

('$_POST[street]','$_POST[city]','$_POST[stateabbr]',' $_POST[zipcode])";

 

should be:

$query="INSERT INTO 'table' (street, city, stateabbr, zipcode ) VALUES

('$_POST[street]','$_POST[city]','$_POST[stateabbr]',' $_POST[zipcode])";
