将html表导出到xlsx文件会将每个html页面内容写入文件中。
我的页面上有四个按钮和其他html代码。其中一个按钮结果是html表，并将其写入xlsx文件。
但除了编写表格内容外，它还会写出label content，Name of all four table和
<h1> Arabic to English </h1>
<form method="post" enctype="multipart/form-data">
*.XLSX <input type="file" name="file" /> <input type="submit" name="submit1" value="Arabic to English" />
</form>
如何停止将除html表之外的内容写入导出的xlsx文件？
这是我的代码：
<label style ="margin-left:30%; margin-bottom:10%; color:red">Please reaload the page before each test [would be fixed]</label>
<div class= "c1">
<div class="row demo-row">

答案 0 :(得分：0)
输出缓冲区，在你的header（）调用之前，或者把标题放在顶部，文件写入将捕获任何输出，所以很明显任何html在你写文件之前都会被捕获，你有3个选择，
在写入文件之前不输出任何内容，（在任何html输出之前移动该代码） - 可能会在它之后捕获，
使用ob_start（），ob_get_clean（）缓存输出，然后在文件后回显它，
最佳选择将文件输出分成单独的php文件，并在需要时通过iframe加载。
你仍然会在同一个文件中强行下载时遇到问题，最好的办法就是发布一个目标作为iframe的表单，然后在iframe中运行文件处理和下载位，用css隐藏iframe。
我很惊讶你没有标题已发送错误。
所以
<form method="post" action="location of file processing .php file" enctype="multipart/form-data" target="iframe" >
*.XLSX <input type="file" name="file" /> <input type="submit" name="submit1" value="Arabic to English" />
</form>
<iframe name="iframe" id="iframe" src="" style="display:none" ></iframe>
将此位放在表格＆＃34; action＆＃34;指出。
<?php
if (isset($_FILES['file'])) {
header('Content-Type: text/html; charset=UTF-8');
require_once "simplexlsx.class.php";
require '../../Arabic.php';
$Arabic = new I18N_Arabic('Transliteration');
$xlsx = new SimpleXLSX( $_FILES['file']['tmp_name'] );
$file="result.xls";
//echo $_POST['submit1'];
header("Content-type: application/vnd.ms-excel");
header("Content-Disposition: attachment; filename=$file");
echo '<table border="1" cellpadding="3" style="border-collapse: collapse">';
$eng = array();
list($cols,) = $xlsx->dimension();
foreach( $xlsx->rows() as $k => $r) {
// if ($k == 0) continue; // skip first row
echo '<tr>';
for( $i = 0; $i < $cols; $i++)
{
if ($_POST['submit2'] = 'Arabic to English')
$temp = $Arabic->en2ar($r[$i]);
else
continue;
echo '<td>'.( (isset($r[$i])) ? $temp : ' ' ).'</td>';
}
echo '</tr>';
}
echo '</table>';
}
?>
对于您的更新，我不确定我只是回答有关输出错误的部分，但我可以告诉您这是不正确的
if ($_POST['submit2'] = 'Enlish to Arabic')
$temp = $Arabic->en2ar($r[$i]);
echo '<td>'.( (isset($r[$i])) ? $temp : ' ' ).'</td>';
暗示
if ($_POST['submit2'] = 'Enlish to Arabic'){
$temp = $Arabic->en2ar($r[$i]);
}
echo '<td>'.( (isset($r[$i])) ? $temp : ' ' ).'</td>';
和
$_POST['submit2'] = 'Enlish to Arabic';
if ($_POST['submit2'] == 'Enlish to Arabic'){...
在这种情况下，你从未在这里设置$ temp变量，$ _POST [＆＃39; submit2＆＃39;]总是等于＆＃39; Enlish to Arabic＆＃39;
你会想要这个（你也做了单身=总是如此）
if ($_POST['submit2'] == 'Enlish to Arabic'){
$temp = $Arabic->en2ar($r[$i]);
echo '<td>'.( (isset($r[$i])) ? $temp : ' ' ).'</td>';
}
