用HTML文本区域中的php变量替换单词

Question

I have. Few forms using general HTML.

One form sends emails to contacts in a database.

How can i make it so when I use something like ##!CONTACT_FORENAME!## it will replace it with the contacts forename from the database (forename column in contacts table)

Answer 1

you have template

$string_template = '
      Hello [username],
      .....
 ';

then you simple replace characters,

$message = strtr($template, array('[username]' => $user_name_from_dtb));

Answer 2

我不知道我是否正确理解了您的问题，但是我会做这样的事情：

 <textarea><?php if (isset($var)) echo $var; ?></textarea>

Answer 3

$body='some text with [variable]';
$regex = "/\[.+?\]/"; // if not use brakets, change this.
if(preg_match_all($regex, $body, $matches, PREG_PATTERN_ORDER)) {
    foreach ($matches[0] as $key => $match) {
        $mvar=substr($match,1,strlen($match)-2); // get the variable name
        $value='this is a real value'; // get the variable value from db;
        $body=preg_replace("#\[".$mvar."\]#s",$value,$body);// replace 
    }
}
