[英]Regular expression for tags in PHP using compound words
Here is my code so far: 到目前为止,这是我的代码:
if (preg_match('/\s/',$tagName)){
$_ErrorMessage = "<div class='alert alert-danger' id='errorBox'>";
$_ErrorMessage.= "<b>Error!</b> La etiqueta no puede contener espacios. Asegúrese de escribirla correctamente.";
$_ErrorMessage.= "</div>";
} elseif(preg_match('/[^A-Z]/i', $tagName)){
$_ErrorMessage = "<div class='alert alert-danger' id='errorBox'>";
$_ErrorMessage.= "<b>Error!</b> La etiqueta no puede contener carácteres especiales. Cáracteres especiales son todos aquellos que no estan dentro del alfabeto. Por favor escríbala de nuevo.";
$_ErrorMessage.= "</div>";
} else {
$insertNewTagQuery = sprintf("INSERT IGNORE INTO solution_tags (SOLUTION_TAGS_NAME)VALUES(LOWER('%s'))", $tagName);
if($DBConnect->query($insertNewTagQuery)){
header("Location:http://127.0.0.1/helpdesk/admin/thankyou.php");
}
}
With the code above, I'm checking whether the string where the tag is, has blank spaces and whether it has any special characters other than the ones in the alphabet. 通过上面的代码,我正在检查标记所在的字符串是否具有空格,并且是否具有除字母之外的任何特殊字符。
Giving it a second thought, and after the engineer in the class said that tags can be compound words and have special characters and numbers such as Internet Explorer
or 'google-chrome' or HTML5
I decided to modify this tiny script. 再三考虑,在班上的工程师说标签可以是复合词并具有特殊字符和数字(例如Internet Explorer
或“ google-chrome”或HTML5
我决定修改此小脚本。
The problem is that I have no experience whatsoever on building regular expressions. 问题是我对构建正则表达式没有任何经验。
How can I do a regular expression with the following criteria? 如何使用以下条件进行正则表达式?
这是一个满足您要求的PHP正则表达式:
/^\b[-a-z \d]*\b$/i
