用于上载多个图像的表单&；通过PHP将数据传输到MySQL数据库

我们正在开发一个内部应用程序，仅用于通过表单和PHP脚本将2个图像和一些文本框上传到MySQL数据库

我们可以得到一个简单的表单，其中只有文本框提交，没有图像字段，我们可以得到一个只有图像字段的表单，并将图像作为BLOB上传到mySQL数据库，但当结合使用2个表单时，我们只能让它上传图像，而不是文本框

请在下面找到我们的php上传脚本的代码，当我们的表单提交时，这会将2个图像字段作为BLOB上传到数据库，但不会将其他文本字段上传到数据库，非常感谢您提供任何帮助，以指出我们的错误：

您的错误可能在于您正在通过彼此使用mysql和mysqli函数。这不管用。要么你使用mysqli，要么你使用mysql。。我会选择mysqli

我是说，你自己检查一下。您可以使用mysqli对它们进行清理，但是在连接到数据库的upload函数中，您可以使用mysql函数

                    // put the image in the db...
                    // database connection
                    mysql_connect($host, $user, $pass) OR DIE (mysql_error());

                    // select the db
                    mysql_select_db ($db) OR DIE ("Unable to select db".mysql_error());

                    // our sql query
                    $sql = "INSERT INTO oohours (sitename, siteaddress, sitepostcode, eqmake, eqmodel, eqdesc, eqserial, eqassetno, eqconttype, brewery, date, onsitetime, offsitetime, custprintname, custsig1, custposition, engname, engsig1)
                    VALUES
                    ('$sitename', '$siteaddress', '$sitepostcode', '$eqmake', '$eqmodel', '$eqdesc', '$eqserial', '$eqassetno', '$eqconttype', '$brewery', '$date', '$onsitetime', '$offsitetime', '$custprintname', '{$imgData1}', '$custposition', '$engname', '{$imgData2}')";

                    // insert the image
                    mysql_query($sql) or die("Error in Query: " . mysql_error());
                    $msg='<p>Image successfully saved in database with id ='. mysql_insert_id().' </p>';

//将图像放入数据库中。。。
//数据库连接
mysql_connect（$host，$user，$pass）或DIE（mysql_error（））；
//选择数据库
mysql_select_db（$db）或DIE（“无法选择db”。mysql_error（））；
//我们的sql查询

价值观

是mysql函数，而其余的mysqli则使用

<?php
$con=mysqli_connect("localhost","Username","Password","outofhours");
// Check connection
if (mysqli_connect_errno()) {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

$maxsize = 10000000; //set to approx 10 MB

$sitename = mysqli_real_escape_string($con, $_POST['sitename']);

$custposition = mysqli_real_escape_string($con, $_POST['custposition']);
$engname = mysqli_real_escape_string($con, $_POST['engname']);

您正在通过彼此使用
MYSQL
和
MYSQLI
函数您好，我们已将其更改为MYSQL，但仍然无法工作：我们是否遗漏了一些内容？Thanksecho拿出$sql，看看它返回了什么，然后通过php my admin抛出它，看看是否有效？我想有些地方还没定下来。我现在看不出问题所在，在浏览完之后。我们已经将其回音出来，所有的值都显示为空白，除了图像值。好的，那么你至少知道哪里出了问题，我告诉你。它们是否都以正确的形式放置？（不是两个单独的表格）？因为您只检查图像是否已设置，而不检查其余数据。您好，在进一步测试（将echo$sitename放入脚本的不同部分）后，我们发现存储了值，但一旦函数启动，该值就不再显示，因此错误在该函数中。
