Hi David, I have 3 csv files that I want to combine into one file and have the same specific structure , so the same headers.
just wondering if you have some sort of template I could work/start from and i could then have a play.
cheers
ok cheers.
right have the below at the moment where its just 2 files at the moment to see it i can get it to work, ive added all the fields , some left black which i assume is ok and some repeated .
how would i go about testing it , how would i execute it , would i use a cron job or can i do it locally or within the browser?
<?php
header("Content-Type: text/plain");
require("MagicParser.php");
function csvsafe($text)
{
return str_replace(array(",","\n","\r")," ",$text);
}
function myRecordHandler($record)
{
global $fields;
$row = array();
foreach($fields as $field)
{
$row[] = csvsafe($record[$field]);
}
print implode(",",$row)."\n";
}
// print header row
print "coupon_description,coupon_excerpt,coupon_category,coupon_tag,coupon_type,stores,date,author,slug
,coupon_code,expire_date,print_url,id,coupon_aff_url,store_aff_url,store_url,store_desc\n";
$fields = array
("description","description","","","","program_name","start_date","","","code","end_date","","","url""url","url","program
_name",);
MagicParser_parse("file1.csv","myRecordHandler","csv|44|1|34");
$fields = array("Offer","Offer","","","","Merchant","Start Date","","","Code","Expiry","","","Signup Link","Signup
Link","Signup Link","Merchant",);
MagicParser_parse("file2.csv","myRecordHandler","csv|44|1|0");
?>Hi Jonny,
To handle empty fields gracefully, replace this line in the code:
$row[] = csvsafe($record[$field]);with:
if ($field)
{
$row[] = csvsafe($record[$field]);
}
else
{
$row[] = "";
}To run the script, create a new folder on your server and save your code there using a suitable filename e.g.
merge.php.
Also put in the folder a copy of MagicParser.php and your file1.csv, file2.csv files etc. as Magic Parser will look for them in the same folder as your script.
Finally, browse to merge.php to view / download the combined CSV...
Cheers
David.
cheers , i just get a HTTP 500 internal server error
Hi jonny,
There was a superfluous comma just inside the closing bracket on this line:
$fields = array
("description","description","","","","program_name","start_date","","","code","end_date","","","url""url","url","program_name",);...which should be:
$fields = array
("description","description","","","","program_name","start_date","","","code","end_date","","","url""url","url","program_name");However that should have caused a parse rather than internal server error but some PHP configurations may use that for security reasons. If still not working after the above correction; email me your script and i'll check it out...
Cheers,
David.
All working now from the file you sent me
Many thanks
Hi Jonny,
Sure - the basic structure (to output CSV to the client) would be something like this:
<?phpheader("Content-Type: text/plain");
require("MagicParser.php");
function csvsafe($text)
{
return str_replace(array(",","\n","\r")," ",$text);
}
function myRecordHandler($record)
{
global $fields;
$row = array();
foreach($fields as $field)
{
$row[] = csvsafe($record[$field]);
}
print implode(",",$row)."\n";
}
// print header row
print "Field1,Field2,Field3,Field4\n";
$fields = array("ABCD","EFGH","IJKL","MNOP");
MagicParser_parse("file1.csv","myRecordHandler","csv|44|1|0");
$fields = array("FIELD1","FIELD2","FIELD3","FIELD4");
MagicParser_parse("file2.csv","myRecordHandler","csv|44|1|0");
$fields = array("FieldA","FieldB","FieldC","FieldD");
MagicParser_parse("file3.csv","myRecordHandler","csv|44|1|0");
?>
The $fields array for each feed contains the 4 field names from each CSV file that map to the 4 fields you want to output (corresponding to the header row Field1,Field2 etc.). When myRecordHandler is called, the contents of each of those fields is then output.
If you're not sure of the Format String required for each of your feeds, check the documentation here or of course upload to the demo tool which will auto-detect the format just like when registering a feed in Price Tapestry...
Hope this helps!
Cheers,
David.
