Pls, let someone help me with this code, When I export, it export the file but start with row2, the first row is excluded.it reads like , header, then row2,3,4 till the end of the row. 请让别人帮我处理这段代码,当我导出时,它导出文件但是从row2开始,第一行被排除在外,它的读法是,标头,然后是row2,3,4直到行末。
<?php
require_once("/includes/session.php");
require_once("/includes/db_connection.php");
require_once("/includes/functions.php");
// Table Name that you want
// to export in csv
$ShowTable = "staff_tab";
$today=date("dmY");
$FileName = "StaffRecord".$today.". csv";
$file = fopen($FileName,"w");
$sql = mysqli_query($connection,("SELECT * FROM $ShowTable LIMIT 500"));
$row = mysqli_fetch_assoc($sql);
// Save headings alon
$HeadingsArray=array();
foreach($row as $name => $value){
$HeadingsArray[]=$name;
}
fputcsv($file,$HeadingsArray);
// Save all records without headings
while($row = mysqli_fetch_assoc($sql)){
$valuesArray=array();
foreach($row as $name => $value){
$valuesArray[]=$value;
}
fputcsv($file,$valuesArray);
}
fclose($file);
header("Location: $FileName");
echo "Complete Record saves as CSV in file: <b style=\"color:red;\">$FileName</b>";
?>
Your call to $row = mysqli_fetch_assoc($sql);
您对
$row = mysqli_fetch_assoc($sql);
调用$row = mysqli_fetch_assoc($sql);
is pushing the internal pointer forward to row 2. Use mysqli_data_seek($sql, 0);
正在将内部指针向前推到第2行。使用
mysqli_data_seek($sql, 0);
to push it back to the start. 将其推回开始。 http://php.net/manual/en/function.mysql-data-seek.php
http://php.net/manual/zh/function.mysql-data-seek.php
...
$sql = mysqli_query($connection,("SELECT * FROM $ShowTable LIMIT 500"));
$row = mysqli_fetch_assoc($sql);
mysqli_data_seek($sql, 0); // return pointer to first row
// Save headings alon
$HeadingsArray=array();
...
maybe this could help as this will include all rows and set headers from the db headers. 可能会有所帮助,因为它将包括所有行并从db标头中设置标头。 This would also force download the file without leaving the page.
这也将强制下载文件而不会离开页面。
$export = mysqli_query ($query) or die ( "Sql error : " . mysqli_error( ) );
// extract the field names for header
$fields = mysqli_num_fields ( $export );
for ( $i = 0; $i < $fields; $i++ )
{
$headers = mysqli_fetch_field($export);
$header .= $headers->name. "\t";
}
// export data
while( $row = mysqli_fetch_row( $export ) )
{
$line = '';
foreach( $row as $value )
{
if ( ( !isset( $value ) ) || ( $value == "" ) )
{
$value = "\t";
}
else
{
$value = str_replace( '"' , '""' , $value );
$value = '"' . $value . '"' . "\t";
}
$line .= $value;
}
$data .= trim( $line ) . "\n";
}
$data = str_replace( "\r" , "" , $data );
if ( $data == "" )
{
$data = "\nNo Record(s) Found!\n";
}
// allow exported file to download forcefully
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=Something.xls");
header("Pragma: no-cache");
header("Expires: 0");
print "$header\n$data";
