php - Inserting values from a drop down list into database -

-

i'm trying insert/update 2 values in database questiontext , type. questiontext being inserted upon adding row, , successful updated when in need to. i'm not successful in either inserting type nor updating it. help?

 case 'addquiz':           $sql = "select id,questiontext,type questioninfo order type desc ";           $result = mysqli_query($con,$sql);          $selectedtable  = "<form method='post' action=''>\n";          $selectedtable .= "<table class='sortable'>\n<tr><th>question</th><th>type</th></tr>\n";           while($row = mysqli_fetch_assoc($result)) {                $rowid = $row['id'];               $text = $row['questiontext'];              $type = $row['type'];               $selectedtable .= "<tr> <td><input type='text' name='questiontext[$rowid]' value='$text'></td><td><select name='type[$rowid]'><option selected='selected'></option><option value='$type'>performace</option><option value='$type'>loyalty</option></select></td></tr>\n";            }          $selectedtable .= "</table>\n";           $selectedtable .= "<input type='submit' name='submit' value='update' style='width:80px; height:30px; text-align:center; padding:0px;'>\n";          $selectedtable .= "<input type='submit' name='addquestion' value='add question' style='width:140px; height:30px; text-align:center; padding:0px;'>\n";          $selectedtable .= "</form>\n";           if(isset($_post['submit'])) {                 foreach($_post['questiontext'] $rowid => $text) {                    $sql = "update questioninfo                           set questiontext = '$text',                               type = '$type'                           id = '$rowid'";                    mysqli_query($con,$sql);              }             }           if(isset($_post['addquestion'])) {                  $sql="insert `questioninfo` (`id`) values (null)";                mysqli_query($con,$sql);         }       break;

actually think bit confused basic life cycle of web page form on it.

the first time page loaded due click on menu or link , therefore there no data process. try , process users inputs if 1 of form's <input type='submit' ....> buttons pressed.

so basic layout of code process form should :-

<?php      if ( $_server["request_method"] == 'post' ) { // or 'get'          // user has pressed submit button          // check required fields present in $_post/$_get          // check button pressed if more 1 button exists         // database access/updates etc based on validated inputs               // store error message in array example used          // in main html generating phase          // set flag or 2 in html generating phase know          // flavor of page want user see          // based on did.     } // end of user input processing       // generate html initial page ( no user input )     // or possibly tailor output depending upon     // user entered , processed above     // , flags set above control      // screen should

if closely, script trying process data wont avilable in case 'addquiz': because when button generate pressed , fields have data in them, wont running case running because button create in case cause case run entirely.

html - Firefox flex bug applied to buttons? -

i'm trying apply flex button on firefox i'm having problem on chrome doesn't happens. this css: .button { display: inline-flex; align-items: center; } as can see in fiddle, "caret" word moved new line, happens if element <button> tag, <div> works expected. http://codepen.io/anon/pen/xblmgx is firefox bug or there css i'm missing? nevermind, looks "mr firefox" doesn't idea... <button> not implementable (by browsers) in pure css, bit of black box, perspective of css. means don't react in same way e.g. <div> would. this isn't specific flexbox -- e.g. don't render scrollbars if put "overflow:scroll" on button, , don't render table if put "display:table" on it. stepping further, isn't specific <button> . consider <fieldset> , <table> have special rendering behavior: data:text/html,<fieldset style="d
