生成报告时phpexcel中的错误

Question

任何人都可以帮助我，当我的表单中的某些字段为空时我正在处理错误，我点击提交（发送到excel），这将弹出我已保存的Excel文件。

但如果我填写表单中的所有输入，则表示没有错误...错误仅显示某些输入为空时我点击按钮。

当前代码：

<?php
if(isset($_POST['send'])){
    require_once 'Classes\PHPExcel\IOFactory.php';
    $filename = 'worksheet.xlsx';
    $title = $_POST['title'];
    mysql_connect("localhost","root","") or die ("cant connect!");
    mysql_select_db("test") or die ("cant find database!");

    $objReader = PHPExcel_IOFactory::createReader('Excel2007');
    $objReader->setReadDataOnly(true);

    $objPHPExcel = $objReader->load($filename);
    $objWorksheet = $objPHPExcel->getActiveSheet();
    $objWorksheet = $objPHPExcel->setActiveSheetIndex(0);
    $name1 = $_POST['name1'];
    $optA1 = $_POST['optA1'];
    $optB1 = $_POST['optB1'];
    $optC1 = $_POST['optC1'];
    $optD1 = $_POST['optD1'];
    $total1 = $_POST['total1'];
    $remarks1 = $_POST['remarks1'];

    $name2 = $_POST['name2'];
    $optA2 = $_POST['optA2'];
    $optB2 = $_POST['optB2'];
    $optC2 = $_POST['optC2'];
    $optD2 = $_POST['optD2'];
    $total2 = $_POST['total2'];
    $remarks2 = $_POST['remarks2'];

    $result = array(
    array(
        $name1,
        $optA1,
        $optB1,
        $optC1,
        $optD1,
        $total1,
        $remarks1
    ),
    array(
        $name2,
        $optA2,
        $optB2,
        $optC2,
        $optD2,
        $total2,
        $remarks2
    )

Answer 1

尝试设置为空而不是空

类似的东西：

$name1 = isset($_POST['name1']) ? $_POST['name1'] : "";
