Question

嘿大家我正在使用TCPDF库来制作PDF。我收到这个错误：

“警告：mysqli_fetch_array（）要求参数1为mysqli_result，boolean给出” “TCPDF错误：某些数据已经输出，无法发送PDF文件”

所以我的问题是，它没有从我的表tbl_mascota获取数据并在td标签中“发布”它

<?php
ob_start();
include('lib/tcpdf/tcpdf.php');
include('controller/conn.php');

$con = get_con();
$query = 'SELECT * FROM tbl_mascota WHERE id_mascota = 1001';
$resultado = mysqli_query($con,$query);
$fila = mysqli_fetch_array($resultado);



//$nombre =  $_GET['nombre'];

// create new PDF document
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);

// set document information
$pdf->SetCreator(PDF_CREATOR);

$pdf->SetTitle('Reporte:'.' '.rand(1,100));
$pdf->SetSubject('TCPDF Tutorial');
$pdf->SetKeywords('TCPDF, PDF, example, test, guide');

// set default header data
$pdf->SetHeaderData(PDF_HEADER_LOGO,0, PDF_HEADER_TITLE.'', PDF_HEADER_STRING, array(0,64,255), array(0,64,128));


// set header and footer fonts
$pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
$pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA));

// set default monospaced font
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);

// set margins
$pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT);
$pdf->SetHeaderMargin(PDF_MARGIN_HEADER);
$pdf->SetFooterMargin(PDF_MARGIN_FOOTER);

// set auto page breaks
$pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);

// set image scale factor
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);

// set some language-dependent strings (optional)
if (@file_exists(dirname(__FILE__).'/lang/eng.php')) {
    require_once(dirname(__FILE__).'/lang/eng.php');
    $pdf->setLanguageArray($l);
}

// ---------------------------------------------------------

// set default font subsetting mode
$pdf->setFontSubsetting(true);

// Set font
// dejavusans is a UTF-8 Unicode font, if you only need to
// print standard ASCII chars, you can use core fonts like
// helvetica or times to reduce file size.
$pdf->SetFont('dejavusans', '', 14, '', true);

// Add a page
// This method has several options, check the source code documentation for more information.
$pdf->AddPage();

// set text shadow effect
$pdf->setTextShadow(array('enabled'=>true, 'depth_w'=>0.2, 'depth_h'=>0.2, 'color'=>array(196,196,196), 'opacity'=>1, 'blend_mode'=>'Normal'));

 function mid(){
 $this->Cell('Reporte'.rand(1,50));

 }
$html = <<<EOF
