I would like to know if it is possible to save form variables after a page is reloaded without submiting.

I am using a reload(form) to reload the page. When I attempt to pass the variables within the reload function, the function will nolonger refresh the page. I have also attempted to use $_Session[''] for the variables, but I am not sure of how to get the value in a text box to $_Session['value1'] when the user enters information into the text box.

I need the $_session['value'] to be updated as soon as anychanges are made to the textbox.

"I would like to know if it is possible to save form variables after a page is reloaded without submiting."

If you aren't submitting the data to the server how can it save the data?

I dont understand what you are trying to do to be honnest.

PHP works on the server side so you need to send the data to the server for any chnages.. It seams that you are trying to make changes happen when the user change data on the form itself before sending it out: That would be the job of Javascript.

I am using a java function to reload the page. I need to carry the values from the php form across the reload.

What I am trying to do is:

When a user enters information into a text box or a list(drop down) the values need to be saved when the page reloads. (page reload will occur when a user makes a list selection, loading different information into a second list based on the option selected from the first.) I need to save any of the information that the user has entered prior to making a selection from the list, so that it can be displayed after the page reloads.

I have the lists working without a problem. I am looking for a way to save the values from a form into java or php, that will allow me to use the values saved after a page reloads.

I thought that I would try to explain things a bit better.

I would like to know if it is possible to save a value from a php form in a session using a java function.


What I am doing:

I have a php form. The form contains a textbox and 2 list menus (drop down box) The second drop down box relies on the selection made in the first.

within the reload() java function I save the value entered in the first list menu (using the onChange="reload(this.form)" ) I pass the variables in the url. The users selection loads values into the second list menu. Where the user can make a second selection. This value is passed using the same method.

What I would like to do is save the textbox (or all the entered values) values in a session using a java function. When the user changes the a value or enters one.

Thanks

I have posted this in the java section also, as it may be more of a java question.

I haven't looked at passing variables between java -> php but it seamed to be a pain when by mistake I got those search result >.<

I use(d) a Javascript double drop down menu on a website I made some times ago.

However I didnt use reload() because there was no point of reloading the same page. The double drop down allow me to make a double selection. I then POST that selection to the next page which then perform a database search and display.

I think what you are trying to do is a bit similar? you want to have multiple drop down which basically when you change drop down 1, the text in drop down 2 change ?

If thats correct, you dont need php @ that stage, you need to look for javascript multiple drop down.

Let me know :)

Edit:
Example of what I think you are trying to do:
http://www.trans4mind.com/personal_d...tripleMenu.htm

I'm doing something similar. Although the list would be far too long to have the data already avalible in the second drop down. The first drop down will have about 300 different values. The second drop down will have up to 60 different values for each value selected in the first drop down.

I have used a mysql query to load the values in the second drop down where they relate to the selection made in the first drop down.

(I reload the page because I need the page to go through the second query (for the second drop down), I'm using an if statment -- if there is a selection made in the first drop down, do this query to load the data in the second drop down list.)

I can't list the total number of values in the second drop down, as there would be about 18000 values in total for the user to search through.

I need to filter them base on the selection from the first drop down, not really a choice for what I need to do(this part is working fine between page loads (using javascript)).

So I need to find some way to save the data in all the text boxes and the list values (preferably without passing them all through the url) There is going to be about 25 text boxes in the form.

There will be two more drop downs lower on the page, using the same info as the drop down boxes above

so you can see why I am avoiding passing everything through the url.

I am just trying to get the 2 drop downs and one text box to work for now. Also -- if the second drop down list is empty, there is no values in the database for that selection in the first drop down, there will be a text box instead of the list.(everything works when I pass the variable through the url)


Thanks again for your input

Hi Can i get help from you guys???

I am facing the problem that Rinventive mention earlier on. That i want to link the 2 list/menu. Can i know how to reload the page by using php? and how do i get the variable from list/menu selected index? I m really at my lost now. Please help..

I m facing the same problem. i select item from first dropdown list and items in second dropdown list get selected. but all form texboxs get empty. need urgent help.

Use PHP to generate the first drop-dowm and in the onchange call a javascript function that submits the form via the get method and not post, then when the page reloads all the previous variables will be available in $_SERVER['QUERY_STRING']
