    Novice - Counting Script

    My prof hasn't gotten back to me and he doesn't seem like even he knows how to do it so I'm posting here for some help. We've barely done any script writing yet and I can't seem to figure out how to go about doing it. He wants us to modify the existing script so that it generates a random number from 1 - 1000 and then counts the number of guesses and outputs how many guesses at the end. It won't open in the browser so I'm not sure what's wrong. Any help would be much appreciated! This is what I have so far: <?php if (!isset($_POST["guess"])) { $message = "Welcome to the guessing machine!"; $_POST["numtobeguessed"] = rand(1,1000); $_POST["counter"] = 0; } else if ($_POST["guess"] > $_POST["numtobeguessed"]) { $message = $_POST["guess"]." is too big! Try a smaller number."; $_POST["counter"]++; } else if ($_POST["guess"] < $_POST["numtobeguessed"]) { $message = $_POST["guess"]." is too small! Try a larger number."; $_POST["counter"]++; } else { // must be equivalent $message = "Well done! It took you '$_POST["counter"]' tries!"; } ?> <html> <head> <title>A PHP number guessing script</title> </head> <body> <h1><?php echo $message; ?></h1> <form action="" method="POST"> <p><strong>Type your guess here:</strong> <input type="text" name="guess"></p> <input type="hidden" name="numtobeguessed" value="<?php echo $_POST["numtobeguessed"]; ?>" ></p> <input type="hidden" name="counter" value="<?php echo $_POST["counter"]; ?>" <p><input type="submit" value="submit your guess"/></p> </form> </body> </html>

  4. I have a form on a page that has checkboxes for a number of entities, including one that is new. I want to determine how many checkboxes were checked for the new entity. The html is: <div id="new" style="display:block;">Which method(s) of valuation would you like to use for this report?<br /> <input type="checkbox" name="method_code['new'][]" value="EE">Excess Earnings<br /> <input type="checkbox" name="method_code['new'][]" value="DCF">Discounted Cash Flow</div> <div id="75" style="display:none;">Which method(s) of valuation would you like to use for this report?<br /><input type="checkbox" name="method_code['75'][]" value="EE" checked="checked" >Excess Earnings<br /> <input type="checkbox" name="method_code['75'][]" value="DCF" checked="checked" >Discounted Cash Flow</div><div id="79" style="display:none;">Which method(s) of valuation would you like to use for this report?<br /> <input type="checkbox" name="method_code['79'][]" value="EE">Excess Earnings<br /><input type="checkbox" name="method_code['79'][]" value="DCF">Discounted Cash Flow</div> <div id="77" style="display:none;">Which method(s) of valuation would you like to use for this report?<br /> <input type="checkbox" name="method_code['77'][]" value="EE">Excess Earnings<br /> <input type="checkbox" name="method_code['77'][]" value="DCF">Discounted Cash Flow</div> I looked for a method of counting the nuber of checked boxes for a given entity and found So, to count only non-empty: count(array_filter($array)); here and here So I implemented that in my code and it doesn't work. I put in the following to debug: echo '<pre>'; print_r($_POST['method_code']); echo '</pre>'; echo "arraycount ".count(array_filter($_POST['method_code']['new']));die(); and I get the following output: Array ( ['new'] => Array ( [0] => EE ) ['75'] => Array ( [0] => EE [1] => DCF ) ['78'] => Array ( [0] => EE ) ) arraycount 0 Why is the count 0? I expect that count(array_filter($_POST['method_code']['new'])) would be one since there is one element in that array.

    Need Help with simple PHP program

    Hey I'm working on a simple program that will take user input from a HTTP form and use that to calculate a few things. I a few problems with my counter and I was wandering if anyone could point out something that could be causing my problem? Also if anyone know how to properly get a count on the positive even int's??? This is what I'm working with. $count = 0; $PosCount = 0; $uname = array($uname1, $uname2, $uname3, $uname4, $uname5, $uname6, $uname7, $uname8); for ($i; $i < count($uname); ++$i) { if ($uname[$i] == '0' || $uname[$i] == null) { //look to see weather its good or bad unset ($uname[$i]); //break that empty field $count = ($count - 1); } $count = $count + 1; if ($uname[$i] % 2 == 0 ) {//Even check $i = $uname[$i]; if ($i == round($i) || $i < 1) { //Pos Check $PosCount = $PosCount + 1; } } } than of course echoing all my desired values (sum, avg, max, min, and pos int count) - Thanks
