Is there a way to maintain mySQL query results, if after I make a selection on a form, and then return to the page, to still have the other selections available? I run a query on a page, and then I created a form with radio boxes to select a person's name from the query result. I process the form, and then when I have a link that returns to the page, the query result list is no longer there. Is there a way to maintain persistance? Thanks.

i have a function where I would like to compare two strings depending on the position of each letter I need to format each letter differently... if the letter is in the right place print it Red if the letter is in the word, but in the wrong place, print it in blue if it's not part of the word at all, make it black how would i do that with the function makeAGuess() below? Also, the printout needs to go in the "guessed" text box which i know i use document.myForm.guessed.value=... function makeAGuess() { var myInput=document.myLingo.input.value; document.myLingo.input.focus(); var cc= " "; if (!document.myLingo.input.value) { alert("Guess a letter.") } else { for(i=0; i<myInput.length; i++) { if(myInput.charAt(i)==theWord.charAt(i)) { document.myLingo.guessed.value=myInput.charAt(i).toUpperCase(); } else document.myLingo.guessed.value=myInput.charAt(i); } } } </script> </head> <body> <form name="myLingo"> <center> <table> <tr> <td> Lingo </td> </tr> <tr> <td align="right"> Get a New Word </td> <td align="left"> <input type="button" name="start" value="New Word" onclick="newGame()" /> </td> </tr> <tr> <td colspan=2 align="center"> <input type="text" name="toGuess" readOnly /> </td> </tr> <tr> <td colspan=2 align="center"> <input type="text" name="guessed" size="43" readonly> </td> </tr> <tr> <td colspan=2 align="center"> <input type="text" name="input" size=35> </td> </tr> <tr> <td colspan=2 align="center"> <input type="button" value="Make Guess" onclick="makeAGuess();"/> </td> </tr> <tr> <td align="right">Guess Count</td> <td align="left"> <input type="text" name="counter" value="" size=2 maxlength=2 disabled> </td> </tr> </table> </center> </form> </body> </html> Any help would be appreciated...

Hello: I would like to navigate through different .php pages. I tried using the <a href> regular link and made sure that the session_start() was on all of the pages, however when i use the links, and return to prior pages, the mysql query is wiped out. How do maintain state when i return back to a page. For example: I query all the people that are in a class, then I click on a specific person to show that person's grades, but when i return back to the main class list, it's no longer there, the sql query is wiped out and doesn't rerun on page load. Thanks, husslela03

Hi: I'm currently attempting to write a word game. It grabs a word from the server by using a button, and then displays it with only the first letter, and then all the rest are blanks. I would like to know the best way to set this us, because when I do a request using AJAX within a javascript function, it completely wipes out the page and just shows the word. Any help would be appreciated of where to start. I can do the rules myself, I just need help with the setup.
