PHP MYSQL將HTML插入MYSQL數據庫

Question

如何將html代碼存儲在mysql數據庫中？我可以在任何地方找到人們可以做到的地方，但沒有人說如何做。我知道我需要使用例子中使用的「mysqli_real_escape_string」去除數據，但不知道如何實際做到這一點。我簡單地放置瞭如下所示的代碼，但它只是讓我誤解了一個錯誤。我知道它是因爲HTML代碼有「」，但我需要在頁面加載時加載這些代碼，所以我如何將代碼插入到數據庫中？一個鏈接或其他東西將是驚人的。

編輯：這裏是完整的代碼，它沒有輸入數據庫中的信息，但沒有給出任何錯誤。在VALUES

       <em>Viruses</em> 
        The computer virus is the most infamous form of malware. It is a self replicating program that infects a system without authorization. Once installed, it will execute itself, infect system files, and attempt to propagate to other systems. The impact of a virus ranges widely from slow system performance to wiping out every file on your computer. <br /><br />

       <em>Worms</em> 
        A computer worm is a self-replicating computer program. It uses a network to send copies of itself to 
    other computers on the network and it may do so without any user intervention. Worms usually exploit a 
    known or zero-day vulnerability that allows them to execute their copies on computers on the same 
    network.<br /><br />

       <em>Adware</em> 
        Adware is a program that causes the host computer to display advertisements that the user did not request. These are frequently in the form of pop-up ads that appear while browsing the Internet and pop-under ads that open in a window hidden beneath the Internet browser's window, according to security4web.com. Another version of adware is a toolbar that attaches to an Internet browser search ability.<br /><br />

       <em>Spyware</em> 
        Spyware collects information from a host computer and sends it to the creator of the program. Spyware can infect a computer as a result of surfing a website that installs it or even as part of programs a user knowingly downloads to use for a different purpose, according to security4web.com. The website notes that freeware (free software) and Internet links advertising spyware-removal programs frequently install spyware.<br /><br />

       <em>Rootkit</em> 
        Rootkits can make it difficult to discover that your computer has been infected by other types of malware. According to h-online.com, a rootkit manipulates files so they are difficult to discover on your computer. This makes it a challenge to find out if a malware process or file is running in the background on your computer because a rootkit program may be preventing you from finding it by browsing folders or searching on your computer file system.<br /><br />

       <em>Trojan Horse</em> 
        A trojan horse is unlike a virus or a worm because it cannot replicate itself, according to spamlaws.com. Instead, it executes itself, and the execution of the file can install additional forms of malware, such as viruses or worms. It can also delete files, eliminate access to specific websites and damage files on the computer.<br /><br />

Answer 1

測試字符串必須用引號包裹，包裹一些報價在你的模板名稱值

if (mysqli_query($cnx, "INSERT into services (template_name, template_code) VALUES ('sidebar_malware', '$city')")) { 

查一查如何輸出MySQL的錯誤，他們會幫你調試這個問題。

Answer 2

使用htmlentities($city);

它會轉換標籤<a>, <img>, <b>，..爲HTML實體。
