php - Echo Session variable not working -



php - Echo Session variable not working -

i have problem passing session variable 'login' other pages. have been using session_is_registered, had move on because of php5.

here login.php

$login=$_post['login']; $heslo=$_post['heslo']; // ochrana proti mysql injection + mysql query $login = stripslashes($login); $heslo = stripslashes($heslo); $login = mysql_real_escape_string($login); $heslo = mysql_real_escape_string($heslo); $md5heslo=md5($heslo); $sql="select * uzivatele login='$login' , heslo='$md5heslo'"; $result=mysql_query($sql); //zjištění id uživatele pro přiřazení session $query = mysql_query("select * uzivatele login='$login'"); $row = mysql_fetch_array($query); $id = $row['id']; // mysql_num_row počítá řádky $count=mysql_num_rows($result); // jestliže výsledek($result) se shoduje s $login $heslo, musí být první řádek if($count==1){ // zapsání proměnných login, přesměrování ná "loggedin_main.php" $_session['login'] = $login; $_session['id'] = $id; header("location:loggedin_main.php"); } else { echo "<div class=\"grey_box\">Špatné jméno nebo heslo, zkuste prosím znovu. <br> <a href=index.php>přejít na hlavní stránku.</a></div>";}

here code set on other pages before everything.

<?php session_start(); $_session['login'] = $login; if (isset($_session[$login])){ header("location:index.php"); } ?>

looks forgot set session_start(); @ top of login.php

php session

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
