将数据插入phpmyadmin时插入空白记录
[英]Inserting a Blank Record When Inserting into data into phpmyadmin
问题描述
i am relatively new to the php coding life and i need some help. 
我对php编码生活比较陌生，我需要一些帮助。 when i am inserting data into my phpmyadmin account it inserts the record i would like but it also inserts just a blank record? 当我向phpmyadmin帐户中插入数据时，它会插入我想要的记录，但它还会插入空白记录？ Suggestions? 建议？ also new to this site if theres any gaps in coding they arent actually there. 如果实际上没有任何编码方面的空白，这对本网站也是新的。

As a word of advice, avoid mysql library, it's obsolete now. 作为建议，请避免使用mysql库，它现在已过时。 Use mysqli or pdo . 使用mysqli或pdo 。

You are using MySQL database. 您正在使用MySQL数据库。 PhpMyAdmin is just a tool to manage the database. PhpMyAdmin只是管理数据库的工具。
The easiest way to solve would be 最简单的解决方法是
if (isset($_POST)) {
$sql="INSERT INTO $tbl_name(year, make, model, price, description, buyme)VALUES('$year', '$make', '$model', '$price', '$description', '$buyme')";
$result=mysql_query($sql);
}

For what you said about your comment "it was inserting a 0 into the year category so i believe it to be that field and ill try that" 对于您对评论的评论， “它在年份类别中插入了0 ，因此我认为这是该字段，请尝试尝试”
If an input field is left blank, then yes, it will insert a blank entry. 如果输入字段留空，则是，它将插入一个空白条目。
That's because you're not checking for empty inputs. 那是因为您不检查空输入。
Use conditional statements like: 使用条件语句，例如：
if(empty($_POST['year'])){
die("You need to fill this.");
}
and wrap your code inside another conditional statement to avoid premature execution. 并将您的代码包装在另一个条件语句中，以避免过早执行。
if(isset($_POST['submit'])){
...
}
