我将使用FPDF库生成PDF报告,但输出为空白。没有显示错误,我该如何解决这个问题?
无论如何,我在LOCALHOST中尝试了这个代码,它运行得很好,但是当我将它上传到云端时,没有输出显示..我试着像这样输出函数..
$this->fpdf->OUTPUT('try.pdf','I'); but nothing happens..
注意:在我的输出中,C:/ backup / employee _ .. php,输出在文件夹中,没有错误,它工作正常..但是当我上传这个,没有输出显示
这是我的控制器:
public function backup_employees_pdf()
{
$this->load->library('fpdf');
define('FPDF_FONTPATH',$this->config->item('fonts_path'));
$this->fpdf =new FPDF('L', 'mm', 'Legal', true, 'UTF-8', false);
$this->fpdf->AliasNbPages();
$this->fpdf->AddPage();
//load data
$data = array();
$row = $this->m_employee->load_data_employees();
$data = $row->result();
// Whatever written here will come in header of the pdf file.

这是细节。我试图解决这个问题,但仍然没有输出。
答案 0 :(得分:0)
我遇到了同样的问题,这是我的解决方案:
而不是使用
$this->fpdf =new FPDF()
我用过
$pdf = new FPDF();
然后你可以使用$ pdf-> ...而不是$ this-> pdf-> ...
以下是一个例子:
define('FPDF_FONTPATH',$this->config->item('fonts_path'));
$this->load->library(array('fpdf','fpdf_rotate','pdf'));
$this->pdf->Open();
$pdf = new PDF();
$pdf->AliasNbPages();
$pdf->AddPage();
$pdf->SetFont('Arial', '', 12);
$pdf->SetDrawColor(0);
$pdf->MultiCell(100,5,"Test\n line of text");
$pdf->Output('test.pdf', 'D');
像魅力一样工作;)
