php - if statement's not working -

-

forgive noobness coding teach myself php (lol)!

code below works form want create. whenever user hits submit button, provided form filled in correctly, text "e-mail sent successfully" message appears @ top of page. if of mandatory fields incomplete or invalid, error message returned underneath corresponding input field , "e-mail sent successfully" message not appear. works last if statement (antispam). essentially, if enter correct answer (3) antispam box, regardless of other fields being filled in or not, "e-mail sent successfully" message appears (it shouldn't other fields not filled out correctly). "e-mail sent successfully" message should appear if mandatory fields completed correctly.

whatever 'if statement' goes @ bottom adhere's same rule (i.e. if name @ bottom of if statements, name need entered correctly e-mail sent message appear). feels though if last if statement passed true, other statements don't work.

<?php  if (isset($_post['submit'])) { $yourname = $_post['yourname']; $organisation = $_post['organisation']; $email_from = $_post['email']; $comments = $_post['comments']; $antispam = $_post['antispam']; $namestring = "/^[a-za-z .'-]+$/"; $emailstring = '/^[a-za-z0-9._%-]+@[a-za-z0-9.-]+\.[a-za-z]{2,4}$/'; $error_message_email = ""; $error_message_name = ""; $error_message_message = ""; $error_message_antispam = "";  if(!preg_match($namestring,$yourname)) {   $error_message_name .= "please enter valid name"; } if(!preg_match($emailstring,$email_from)) {   $error_message_email .= "please enter valid e-mail address"; } if(strlen($comments) < 4) {   $error_message_message .= "please enter valid message"; } if($antispam != "3") {    $error_message_antispam .= "please enter valid answer"; } else {   echo "e-mail sent successfully"; }  } else {  $yourname=""; $organisation=""; $email_from=""; $comments=""; $antispam=""; $error_message_email = ""; $error_message_name = ""; $error_message_message = ""; $error_message_antispam = ""; }     ?>   <form name="htmlform" method="post" action="ifandelse.php">               <table width="650px">               <tr>                 <td>                   <label for="yourname"><font color="#ff0000">*</font>name:</label>                 </td>                 <td>                   <input  type="text" name="yourname" value="<?php echo$yourname;?>"        maxlength="50" size="40"><br>                       <div class="warning">                         <?php print $error_message_name;?>                       </div>                 </td>               </tr>                <tr>                 <td>                   <label for="organisation">organisation:</label>                 </td>                 <td>                   <input  type="text" name="organisation"  value="<?php echo$organisation;?>"maxlength="50" size="40">                 </td>               </tr>                <tr>                 <td>                   <label for="email"><font color="#ff0000">*</font>e-mail address:</label>                 </td>                 <td>                   <input  type="text" name="email" value="<?php echo$email_from;?>" maxlength="80" size="40"><br>                     <div class="warning">                       <?php print $error_message_email;?>                     </div>                 </td>               </tr>                <tr>                 <td valign="top">                   <label for="comments"><font color="#ff0000">*</font>message:<br></label>                 </td>                 <td>                   <textarea name="comments" rows="8" cols="60"><?php echo$comments;?></textarea><br>                     <div class="warning">                       <?php print $error_message_message;?>                     </div>                 </td>               </tr>                <tr>                 <td colspan="2">                       <font color="#ff0000">*</font>to avoid unwanted spam, please answer following question correctly: 2 + 1 = <input type="text" name="antispam" value="<?php echo$antispam?>" maxlength="100" style="width:30px"><br>                     <div class="warning">                       <?php print $error_message_antispam;?>                     </div>                 </td>               </tr>                <tr>                 <td>                 </td>                 <td style="text-align:center;">                   <input type="submit" class="formsubmit" name="submit" value="submit form">                 </td>               </tr>              </table>           </form>

be grateful help, i've had several friends , still can't figure out why it's doing this. have tried nesting 'if statements' differently, changing if statement's else if, etc no joy :(

i've looked on forums , can't find solution works me.

you should use variable know if there error (or more one) @ end of verifications. code below give general idea : 

$iserror = false;    if (!preg_match($namestring, $yourname)) {     $error_message_name .= "please enter valid name";     $iserror = true; }  if (!preg_match($emailstring, $email_from)) {     $error_message_email .= "please enter valid e-mail address";     $iserror = true; }  if (strlen($comments) < 4) {     $error_message_message .= "please enter valid message";     $iserror = true; }  if ($antispam != "3") {     $error_message_antispam .= "please enter valid answer";     $iserror = true; }    if ($iserror) {     //do wathever have } else {    //send mail    echo "e-mail sent successfully"; }

c++ - Function signature as a function template parameter -

i'd use function signature template argument. works great classes, when try same trick function templates, msvc throws error: error c2768: 'func' : illegal use of explicit template arguments here's code: template <typename signature> void func(); template <typename r, typename a1> void func<r(a1)>(); what should make work? you cannot partially specialize function template, not supported language. can create partially specialized class template static member function, , possibly trampoline function instantiate class template , invoke static function. something this: namespace detail { template<typename signature> struct helper; template<typename r, typename a1> struct helper<r(a1)> { static void call() { // stuff r , a1... } }; } template<typename signature> void func() { detail::helper<signature>::call(); }

algorithm - What are some ways to combine a number of (potentially incompatible) sorted sub-sets of a total set into a (partial) ordering of the total set? -

-
i have sorting problem i'm pretty sure doesn't have canonical "answer" - has number of different approaches, each pros/cons. i'm interested in hearing different approaches. suppose bunch of people {p_i | i=1,...,m} ranking favorite ice cream flavors. in total there n different flavors, single person p_i ranks n_i << n flavors or familiar with. i'm interested in combining these sub-rankings plausible overall ranking of n flavors. for concrete situation: m , n both 1000 (by coincidence), , each n_i 20 . can assume there's enough overlap in flavors people rank such no flavor "isolated". again, i'm interested in hearing different ways approach this, if there isn't single clear answer. thanks! one way approach problem construct directed cyclic graph representing of constraints on ordering of elements. nodes in graph represent different elements compared , have edge first node second node if had ranked first e...

there's function on page want call after loads. not own page, can't insert html it. can please provide specific examples how chrome extension or greasemonkey?
