Minule sme sa venovali vytvoreniu formul\u00e1ra pre odoslanie e-mailovej spr\u00e1vy. Probl\u00e9mom uveden\u00e9ho pr\u00edkladu ale bolo, \u017ee \u00fadaje v spr\u00e1ve nemuseli by\u0165 spr\u00e1vne vyplnen\u00e9, ba polia vo formul\u00e1ri mohli by\u0165 pr\u00e1zdne a e-mail bol napriek tomu odoslan\u00fd. Posielanie nevyplen\u00fdch spr\u00e1v, nespr\u00e1vne vyplnen\u00fdch alebo posielanie spamu s\u00fa v\u0161ak nedovolen\u00e9 a je to potrebn\u00e9 nejako o\u0161etri\u0165. V \u010fal\u0161om uv\u00e1dzame nieko\u013eko pr\u00edkladov ako sa to d\u00e1 v php k\u00f3de o\u0161etri\u0165:<\/p>\n

1. Overenie spr\u00e1vnosti mailovej adresy<\/h5>\n
<?php\r\n if (isset($_POST[\"email\"]))\r\n {\r\n if (eregi(\"^[[:alnum:]][a-z0-9_.-]*@[a-z0-9.-]+\\.[a-z]{2,4}$\",$_POST['email']))\r\n echo \"Zadan\u00fd email je OK.\";\r\n else\r\n echo \"Chybn\u00fd email!\";\r\n }\r\n ?>\r\n \r\n <FORM ACTION=\"mail.php\" method=post><BR>\r\n Zadajte e-mail: <INPUT type=\"text\" name=\"email\"><br>\r\n <INPUT type=\"submit\" value=\" Odosla\u0165 \">\r\n <\/FORM>\r\n<\/pre>\n
inou variantou m\u00f4\u017ee by\u0165 tento pr\u00edklad:<\/p>\n
<?php\r\n if ($_POST[\"email\"]!=\"\")\r\n {\r\n if (ereg(\"^(.+)@(.+)\\\\.(.+)$\", $_POST[\"email\"]))\r\n echo \"Zadan\u00fd email je OK.\";\r\n else\r\n echo \"Chybn\u00fd email!\";\r\n }\r\n ?>\r\n \r\n <FORM ACTION=\"mail.php\" method=post><BR>\r\n Zadajte e-mail: <INPUT type=\"text\" name=\"email\"><br>\r\n <INPUT type=\"submit\" value=\" Odosla\u0165 \">\r\n <\/FORM><\/pre>\n
2. Overenie \u010di je vyp\u00edsan\u00fd predmet spr\u00e1vy a ostatn\u00e9 \u00fadaje a jednoduchou antispamovou ochranou tzv. capcha<\/h5>\n
