Question

我想通过选择多个公司名称使用多个选择复选框来过滤表格，表格将显示与所选复选框相关的记录。它只能选择一个复选框并仅显示一个相关记录，但不能选择多个复选框。

<form name="frmSearch" id="frmSearch" method="post" action="">

  <label>Company Name&nbsp;</label>
  <select id="multiple-checkboxes" multiple="multiple" name="COMPANYNAME">
    <?php
        $query = mysqli_query($conn_connection, "SELECT * FROM sl_iv GROUP by COMPANYNAME");

        while ($row = mysqli_fetch_assoc($query)) {
            echo "<option value='".$row["COMPANYNAME"]."'".($row["COMPANYNAME"]==$_POST["COMPANYNAME"] ? " selected" : "").">".$row["COMPANYNAME"]."</option>";
        }
    ?>
  </select>
  <br></br>

  <button type="submit" id="submit" class="btn btn-info btn-sm"><span class="glyphicon glyphicon-search"></span> Search</button>
  <a href="cust_due_list.php">
    <button type="button" class="btn btn-success btn-sm"><span class="glyphicon glyphicon-refresh"></span> RESET</button>
  </a>

  <br></br>

  <table id="table">
    <center>
      <thead>
        <tr class="item-row">
          <th width="15%" style="text-align:center"><span>Doc No.</span></th>
          <th width="10%" style="text-align:center"><span>Due</span></th>

当您收到多选POST时，它会以数组形式出现，因此您应该使用＆＃34; IN＆＃34;您的mysql请求中的运算符而不是比较。尝试更改代码的一部分：

if(isset ($_POST['COMPANYNAME'])) {
   $COMPANYNAME = $_POST['COMPANYNAME'];
   $COMPANYNAME = is_array($COMPANYNAME) ? $COMPANYNAME : [$COMPANYNAME];

   $companiesParam = '\''. join("', '", $COMPANYNAME) . '\'';
   $fetch = "SELECT sl_iv.DOCDATE, ar_iv.DUEDATE, payment_terms.terms, sl_iv.DOCNO, sl_iv.COMPANYNAME, ar_iv.DOCAMT, ar_iv.PAYMENTAMT FROM `sl_iv` Inner Join `ar_iv` On ar_iv.DOCNO = sl_iv.DOCNO Inner Join `payment_terms` On ar_iv.TERMS = payment_terms.id WHERE sl_iv.COMPANYNAME IN (".$companiesParam.") or sl_iv.DOCDATE <= '".$from."'";
   $result = mysqli_query($conn_connection,$fetch)or die("MySQL error: " . mysqli_error($conn_connection) . "<hr>\nQuery: $fetch");
}

多选复选框以显示表记录
