Hi to all gurus, Here is a small program in flash which calls values from PHP and displays them correctly. path = "http://localhost/xampp/nwjv/php/"; //declare path to php files lvOut = new LoadVars(); //create lv object sending variables OUT to php lvIn = new LoadVars(); //create lv object receiving variables IN from php lvIn.onLoad = function (success) { if(success) { //PHP variable value to textbox InVal = lvIn.returnVal; InTxt = lvIn.retVal; output.text = InVal; output1.text = InTxt; /* output1.text = "No Value"; if(InTxt == 'lo' ) { output1.text = "Low Value"; } if(InTxt == 'hi') { output1.text = "High Value"; } */ }else{ //...or notify of failure output.text = "fail"; } } myBtn.onRelease = function(){ //assign user-input value to lv property called years lvOut.years = years.text; //send to a blank window // lvOut.send(path + "dogyears_new1.php",lvIn,"GET"); lvOut.sendAndLoad(path + "dogyears_new1.php",lvIn,"GET"); }; And the simplest PHP code PHP Code: <?php$calculation = $_GET["years"]*2; if($calculation <=10 ) $retVal="lo"; if($calculation > 10) $retVal="hi"; echo "&returnVal=$calculation &retVal=$retVal" ;?> PHP returns two values which are collected by flash in variables InVal and InTxt. The values collected are correct and are displayed thus in the 2 output boxes. Now if i the commented out If then block is activated by removing the /* */ from around it and the program is run, clearly the if then blocks fail since the comparison of InTxt fails. It completely fails me why this is happening. While I can display the values correctly, I can't use them in conditional loops. I have even tried them in switch case statements with the same frustrating result. ( The output1.text remains equal to "No Value" when it should change to either "High Value " or "Low Value") Earlier I was using numbers and when that failed I tried to use strings since I thought that for some reason PHP returns everything as strings. Please note that the command typeof InTxt (not used in the above code) returns a String suggesting that InTxt is a string variable. But as can be seen, even the string comparison fails. Can someone please comment on this behavior and suggest a solution. Thanks loads all !
