E-mailov² klient pre webmail v PHP - adresßr a doplnkovΘ funkcie

V tomto zßvereΦnom Φlßnku o tvorbe webmailu vßs oboznßmim s doplnkov²mi funkciami, vymazßvanφm e-mailov, Φφtanφm odoslan²ch e-mailov a adresßrom.

PoslednΘ s·bory tohto webmailu s· nasledovnΘ:

delete.php - s·bor pre vymazßvanie e-mailov
delete_address.php - vymazßvanie adries z adresßra
insert_address.php - vkladanie adries do adresßra
read_sent.php - Φφtanie odoslan²ch sprßv
select_address.php - v²ber viacer²ch adries prijφmate╛ov e-mailu
send_to_address.php - tieto adresy upravφ a vlo₧φ do formulßra na pφsanie sprßv (new.php)
sent.php - odoslanΘ sprßvy

Vymazßvanie e-mailov (delete.php)

ZaΦneme od prvΘho s·boru delete.php, ktor² vymazßva e-mailovΘ sprßvy. Zdrojov² k≤d s·boru a funkcie:

<?php
  session_start();
  require "./functions.php";
  html_header();
  delete_message($id);
  html_footer();
?>

// functions.php
<?php
function delete_message($id)
{
  global $userid;
  $imap = open();
  if(!$imap) return false;

  $num_id = count($id);
  if($num_id>0):
    for($i=0;$i<$num_id;$i++):
      imap_delete($imap,$id[$i]);
    endfor;
    imap_expunge($imap);
    if($num_id==1) echo "<div align='center' class='middle'>Sprßva bola vymazanß.</div>";
    elseif($num_id>1) echo "<div align='center' class='middle'>Sprßvy boli vymazanΘ.</div>";
    imap_close($imap);
  else:
    echo "<div align='center' class='warning'>Äiadna sprßva nebola vybranß k vymazaniu.</div>";
  endif;
}
?>

Mazanie e-mailov²ch sprßv prebieha vo funkcii delete_message() na zßklade identifikaΦnΘho Φφsla sprßvy. Vymazßva¥ sa dß viac sprßv zßrove≥, premennß $id je teda pole. Vstup je z v²beru sprßv, kde oznaΦφme tie, ktorΘ chceme vymaza¥ a formulßr odoÜleme. Vo funkcii m⌠₧ete nßjs¥ tieto IMAP funkcie:

int imap_delete(int spojenie, int cislo_spravy); - funkcia oznaΦφ sprßvu pre zmazanie
int imap_expunge(int spojenie); - funkcia vyma₧e sprßvy oznaΦenΘ funkciou imap_delete()
int imap_close(int spojenie, int moznosti); - uzatvorφ spojenie

Adresßr

Adresßr je u₧itoΦnß vec, ktorß nebude ch²ba¥ ani v naÜom webmaile. Ten nßÜ bude schopn² pridßva¥, vymazßva¥ a hlavne zobrazova¥ a prakticky vyu₧φva¥ kontakty. ZaΦneme pekne od zaΦiatku - pridßvanie (insert_address.php):

<?php
  session_start();
  require "./functions.php";
  html_header();
  insert_address_form($_GET);
  html_footer();
?>

// functions.php
function insert_address_form($form)
{
  global $userid;

  $form['name'] = trim($form['name']);
  $form['mail'] = trim($form['mail']);
  if(!isset($form['sent'])):
    ?>
    <form action="insert_address.php" method="get">
    <table cellpadding="0" cellspacing="0" border="0">
    <tr>
      <td><div align="left" class="middle">Meno </div></td>
      <td><input type="text" class="textinput" name="name" /></td>
    </tr>
    <tr>
      <td><div align="left" class="middle">Adresa </div></td>
      <td><input type="text" class="textinput" name="mail" value="<?php echo form['mail']?$form['mail']:""?>" /></td>
    </tr>
    <tr>
      <td colspan="2" align="center"><button type="submit" class="button">Vlo₧i¥</button></td>
    </tr>
    </table>
    <input type="hidden" name="sent" value="1" />
    </form>
    <?php
  else:
    db_connect();
    $query = "insert into address values('','$userid','$form[name]','$form[mail]')";
    $result = mysql_query($query);
    if(!$result)
    {
      echo "<div class='warning' align='center'>Kontakt sa nepodarilo vlo₧i¥.</div>";
      return;
    }
    echo "<div class='warning' align='center'>Kontakt bol ·speÜne pridan².</div>";
  endif;
}

Jednoduchß funkcia, ktorß umo₧≥uje vklada¥ novΘ kontakty. Pokia╛ je formulßr odoslan², tak sa ·daje spracuj· - vlo₧ia do databßze. V opaΦnom prφpade sa zobrazφ formulßr na vkladanie nov²ch kontaktov.

Vymazßvanie kontaktov bude prebieha¥ v s·bore delete_address.php:

<?php
  session_start();
  require "./functions.php";
  html_header();
  delete_address($_GET);
  html_footer();
?>

// functions.php
function delete_address($form)
{
  global $userid;
  $address = trim($form['address']);
  if(empty($address)):
    db_connect();
    $query = "select * from address where userid = '$userid'";
    $result = mysql_query($query);
    $num_result = mysql_num_rows($result);
    if($num_result>0):
      ?>
      <select name='address' class='select'>
        <option value='false'>--vyber--</option>
        <?php
        for($i=0;$i<$num_result;$i++):
          $name = mysql_result($result,$i,"name");
          $address = mysql_result($result,$i,"mail");
          echo "<option value='$address'>$name <".$address."></option>";

        endfor;
        ?>
      </select>
       
      <button class="button" type="submit">Vymaza¥</button>
      <?php
    else:
      echo "<div class='warning' align='center'>V adresßri nemßte ₧iadne zßznamy.</div>";
    endif;
  else:
    db_connect();
    $query = "delete from address where userid = '$userid' and address = '$address'";
    $result = mysql_query($query);
    if(!$result)
    {
      echo "<div class='warning' align='center'>Zßznam sa nepodarilo vymaza¥.</div>";
      return;
    }
    else echo "<div class='middle' align='center'>Zßznam bol ·speÜne vymazan².</div>";
  endif;
}

Vymazßvanie prebieha tie₧ ve╛mi jednoducho - kontakt, ktor² chceme vymaza¥, vyberieme z formulßrovΘho prvku select a formulßr odoÜleme. Funkcia ako v predoÜlom prφpade aj v tomto funguje na princφpe, ₧e ak sme nieΦo posielali, tak sa spracuje, pokia╛ nie, tak sa zobrazφ formulßr.

Adresßr sl·₧i hlavne k v²beru adries prijφmate╛ov sprßvy. To sa odohrßva v s·bore select_address.php:

<?php
  session_start();
  require "./functions.php";
  html_header();
  select_address($_GET);
  html_footer();
?>

// functions.php
function select_address($form)
{
  global $userid;
  $address = trim($form['address']);
  if(empty($address)):
    db_connect();
    $query = "select * from address where userid = '$userid'";
    $result = mysql_query($query);
    $num_result = mysql_num_rows($result);
    if($num_result>0):
      ?>
      <form action='send_to_address.php' method='post'>
      <div class='middle'>
      <?php
      for($i=0;$i<$num_result;$i++):
        $name = mysql_result($result,$i,"name");
        $address = mysql_result($result,$i,"mail");
        echo "<input type='checkbox' name='adresy[]' value='$address' />$name <".$address."> <br />";

      endfor;
      ?>
      </div>
      <button class="button" type="submit">Posla¥</button>
      </form>
       
      <?php
    else:
      echo "<div class='warning' align='center'>V adresßri nemßte ₧iadne zßznamy.</div>";
    endif;
  else:
    db_connect();
    $query = "delete from address where userid = '$userid' and address = '$address'";
    $result = mysql_query($query);
    if(!$result)
    {
      echo "<div class='warning' align='center'>Zßznam sa nepodarilo vymaza¥.</div>";
      return;
    }
    else echo "<div class='middle' align='center'>Zßznam bol ·speÜne vymazan².</div>";
  endif;
}

V²ber adries sa realizuje zaÜkrtnutφm prvku checkbox. Ten mß nßzov adresy[], Φφm docielime to, aby na v²stupe bolo pole, ktorΘ bude obsahova¥ adresy prijφmate╛ov.

Posledn² s·bor t²kaj·ci sa adresßru je send_to_address.php, ktor² je vizußlne toto₧n² s new.php, kde sa pφÜe novß sprßva. Tento s·bor len vytvßra adresu odosielate╛a z v²beru adries z predoÜlej strßnky select_address.php.

<?php
  session_start();
  require "./functions.php";
  html_header();
  $to = get_address($_POST['adresy']);
  show_form($to);
  html_footer();
?>

// functions.php
function get_address($adresy)
{
  $count = count($adresy);
  if($count==0) return '';
  for($i=0;$i<$count;$i++):
    if($i==($count-1)) $to .= $adresy[$i];
    else $to .= $adresy[$i].",";
  endfor;
  return $to;
}

Funkcia get_address e-mailovΘ adresy zoradφ za sebou, oddelφ Φiarkou a ulo₧φ do premennej $to. T·to potom predß funkciφ show_form(), ktor· sme si popφsali u₧ v prvom Φlßnku.

╚φtanie odoslan²ch mailov (sent.php)

Webmail nßm dovolφ si Φφta¥ aj odoslanΘ e-mailovΘ sprßvy. Tieto sa bud· uklada¥ do databßzy. K≤d s·boru sent.php k zobrazovaniu a Φφtaniu odoslan²ch mailov vyzerß nasledovne:

<?php
  session_start();
  require "./functions.php";
  html_header();
  list_sent($_GET);
  html_footer();
?>

// function.php - funkcia list_sent();
function list_sent($form)
{
  global $userid;
  if(empty($form['orderby'])) $form['orderby'] = "date";
  db_connect();
  $query = "select * from sent where userid = '$userid' order by $form[orderby] desc";
  $result = mysql_query($query);
  $num_result = mysql_num_rows($result);
  if($num_result>0):
    echo "<table cellpadding='0' cellspacing='0' border='0'>";

DoplnkovΘ funkcie

Na zßver eÜte nesm· ch²ba¥ spomφnanΘ doplnkovΘ funkcie:

function address()
{
  global $userid;
  db_connect();
  $query = "select * from accounts where userid = '$userid'";
  $result = mysql_query($query);
  $num_result = mysql_num_rows($result);
  if($num_result>0) $address = mysql_result($result,0,"address");
  return $address;
}

function name()
{
  global $userid;
  db_connect();
  $query = "select * from accounts where userid = '$userid'";
  $result = mysql_query($query);
  $num_result = mysql_num_rows($result);
  if($num_result>0) $name = mysql_result($result,0,"name");
  return $name;
}

Funkcia address() vyberie z databßzy vaÜu e-mailov· adresu, ktorß je potrebnß pri odosielanφ e-mailov. Funkcia name() vyberß z databßze meno, ktorΘ sa zobrazφ prijφmate╛ovi sprßvy.

K dispozφcii s· vßm zdrojovΘ s·bory celΘho webmailu. M⌠₧ete k nemu jednoducho prirobi¥ prihlasovacφ systΘm s registrßciou, kde budete m⌠c¥ vytvori¥ viacero e-mailov²ch k⌠nt pre viacer²ch u₧φvate╛ov.
