  6.     if (isset($_POST[$ifpost])) {

  8.             $p = $_POST[$ifpost];
  9.         } else {

Если не отправлена форма с $_POST или $_GET, то строки вида
PHP
  1. <?php
  2. $text = $_POST['text'];
  3. ?>

вызывают ошибку.
Нужно писать так:
PHP
  1. <?php
  2. if (isset($_POST['text']))  $text = $_POST['text']; else $text = "";
  3. ?>

или так:
PHP
  1. <?php
  2. $text = ""; if (isset($_POST['text']))  $text = $_POST['text'];
  3. ?>

Чтобы не писать каждый раз такую конструкцию, проше написать, используя функцию:
PHP
  1. <?php
  2. $text = ifpost($ifpost='text', $no='', $yes='');
  3. ?>

Или так:
PHP
  1. <?php
  2. $text = ifpost('text', '', '');
  3. ?>

Или так:
PHP
  1. <?php
  2. $text = ifpost($ifpost='text', $no='');
  3. ?>

Или так:
PHP
  1. <?php
  2. $text = ifpost('text', '');
  3. ?>


Такая функция вернёт значение введенного $_POST['text'], если он введён в форме, или заданное пустое значение ($no='').
Если в случае невведения в форме нужно значение не пусто ($no=''), а ноль ($no='0'), следует написать так:
PHP
  1. <?php
  2. $text = ifpost($ifpost='text', $no='0', $yes='');
  3. ?>

Или так:
PHP
  1. <?php
  2. $text = ifpost($ifpost='text', $no='0');
  3. ?>

Или так:
PHP
  1. <?php
  2. $text = ifpost('text', '0', '');
  3. ?>

Или так:
PHP
  1. <?php
  2. $text = ifpost('text', '0');
  3. ?>


Третье значение $yes='' нужно для форм с чекбоксами, которые в случае введения в форме принимают значение 1, а в случае невведния - 0.
Чтобы не писать каждый раз такую конструкцию:
PHP
  1. <?php
  2. if (isset($_POST['checkbox_agree']))  $checkbox_agree = '1'; else   $checkbox_agree = '0';
  3. ?>

Проще написать, используя функцию:
PHP
  1. <?php
  2. $checkbox_agree = ifpost($ifpost='checkbox_agree', $no='0', $yes='1');
  3. ?>

Или так:
PHP
  1. <?php
  2. $checkbox_agree = ifpost('checkbox_agree', '0', '1');
  3. ?>


C $_GET всё делается аналогично, только для введения $_POST требуется указать в форме method='post' :
[code]<form name='submit_form' method='post' action=''>[/code]

Дополнение:
А для загрузки файлов ещё надо указать enctype='multipart/form-data' :
[code]<form name='submit_form' method='post' action='' enctype='multipart/form-data' >[/code]

Функции ifget() и ifpost() уместно использовать с функцией stripslashes().
Для введения любых значений в базу данных у всех значений в php обычно экранируются кавычки. Например так:
$text = addslashes($text);
Функция stripslashes() удаляет обратные слеши, например, из текста
PHP
  1. <?php
  2. <td class='white'>
  3. ?>

делает текст
PHP
  1. <?php
  2. <td class='white'>
  3. ?>


Не всегда при выводе текста в форму слеши удаляются (по вине веб-мастеров).
Поэтому я обычно пишу так (для очень редкого случая, когда обратных слешей два или три):
PHP
  1. <?php
  2. $text = stripslashes(stripslashes(ifpost('text', '')));
  3. ?>
