i have created text fields dynamically by clicking a button now problem is that i want to save the value of these text field into database. i m using java script with PHP's framework codeigniter. the code is as follows
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml">
i'm busy making a site for a audiovisual company and i'm stuck at the CMS system by adding pictures to a project page. Adding one single photo isn't the problem but I want a button to add a new file input field and insert that second (or thirth, fourth etc etc) into a new row in the database.... The script that i'm using right now, clones the input field but doesn't "activates" it.... You can't select a file....
I have a dropdown (picklist) on the page, and when the user selects one of the company names in the list the onChange event fires and kicks in some AJAX to get the company's details from the database. The details are just the various locations of each company.
The way I am doing it now I have a simple div on the page below the picklist and I am using PHP to draw out the entire HTML, including the values sought from the database, and then just using innerHTML on the div to dump the info in there.
I need to pass user input from a form to one database field. I'm relatively new to JS but the idea I had was to have several form elements and use JS to collect the users input and send all the values through a hidden element. What's happening is the variable names are being sent rather than the values. The code below is only passing to the next page. Limitations: I am editing an intranet site built by a 3rd party so a lot of the files we've been given are encrypted. I cannot change the method to post.

this link will take you to the product, but the drop downs from the menus haven't changed, just the price and the quantity.
i need to know of a way of selecting from the database and it be able to change the drop downs from a specific url.
our problem is we need to populate a select option in order of the one we send.

The following form validation script works, currently if one of the five fields are completed, a message appears the remaining field(s) must be completed etc. Although the information the user has inputted in the first field is cleared. How can this information be available, if there is one problem in the form it doesn't make sense that the user must re-input all the information again. I look forward to hearing your response,
i am trying to create a form that where the page will not refresh if the form is submitted specially if the user inputs any errors in the form my problem is i do not know how to send multiple variables using jquery to a php file i saw somewhere that in order to do this you need to concatenate the variables you will be sending this is the code i am using

I have a form.On the form I have a drop down box that allows the user to select a data set to work with (A or B). The table loads just fine and all is right with the world. No problems there.What I need is for the user to be able to edit the data set and have those changes written directly back to the mySQL database. They also need the option of deleting a record entirely.I know how to do all the database queries, updates, etc. I just don't know how to write the ajax forms to accomplish this.
