Question

我已经列出了公司名单，包括他们的领域和规模。我做了几个复选框以便过滤掉它们

<tr>
<td><input type="checkbox" name="field[]" value="Water">Water </td>
<td><input type="checkbox" name="size[]" value="Small">Small </td>
</tr>
<tr>
<td><input type="checkbox" name="field[]" value="Energy">Energy </td>
<td><input type="checkbox" name="size[]" value="Medium">Medium </td>
</tr>
<tr>
<td><input type="checkbox" name="field[]" value="Wind">Wind </td>
<td><input type="checkbox" name="size[]" value="Big">Big </td>
</tr>
<tr>
<td><input type="checkbox" name="field[]" value="Earth">Earth </td>

这是PHP复选框搜索：

if(isset($_REQUEST['submit']))
{               

    //if( count($_POST['field']) > 0)
    if (isset($_POST['field']))
    {       
        $field =  implode(',',$_POST['field']);
        $str = "AND company_field LIKE '$field'";
    }
    else
    {
        $str = "";
    }

    //if( count($_POST['size']) > 0 )
    if (isset($_POST['size']))
    {           
        $size =  implode(',',$_POST['size']);
        $str1 = "AND company_size LIKE '$size'";
    }
    else
    {
        $str1 = "";
    }
    $run = "SELECT * FROM company WHERE 1=1 ".$str.$str1;
    $reslt = mysql_query($run);

如果我没有选择任何一个或选择每个列中的一个，则复选框可以正常工作。但是当我在1列中选择2个或更多时，查询将如下所示： SELECT * FROM company_info WHERE 1=1 AND company_size LIKE 'M, B'我知道这个查询错了，应该是 WHERE 1=1 AND company_size LIKE 'M' OR company_size LIKE 'B'。所以我正在为此寻找解决方案或代码。任何帮助表示赞赏。谢谢！

Answer 1

你可以使用，

$ field = implode（'，'，$ _ POST ['field']）; $ str =“AND company_field IN（”。$ field。“）”;

Answer 2

只需尝试此

<?php

if(isset($_REQUEST['submit']))
{               
    $str = NULL;
    //if( count($_POST['field']) > 0)
    if (isset($_POST['field']))
    {       
        $field  = implode(',',$_POST['field']);
        $str  =" AND company_field IN ($field) ";
    }

    //if( count($_POST['size']) > 0 )
    if (isset($_POST['size']))
    {           
        $size =  implode(',',$_POST['size']);
        $str  .= " AND company_size IN ($size) ";
    }

    $run = mysql_query("SELECT * FROM company WHERE ".$str);



?>
