I'm using cakephp XLS helper to generate Excel report in my project.
But the generated file is giving warning message in windows system as below.
Similarly the same file displays the entire xml mark-up in open-office on linux as below.
Part of the view file code is as below.
$xls->setHeader('Report_'.date('Y_m_d'));
$xls->addXmlHeader();
$xls->setWorkSheetName('Enrollment Report');
//1st row for columns name
$xls->openRow();
$xls->writeString('ID');
$xls->writeString('Zipcode');
My Client wants a proper excel report with-out any warnings in windows.
Please suggest me any excel helper for cakephp which will generate proper excel file on all the platform and different application.
Your problem is that you are using a helper that puts your data in xml format. Excel can read XML and HTML but with a warning. You should use the one that Ivo suggested in the comments. LINK
This helper really makes an xls valid format, that complys with open office and office. Also, this helper relies on PHPExcel class that is constantly updated here so your code will be easy to upgrade if needed.
Remember to follow instructions given in the helper page.
I've tried a lot of this xls helper for cakephp, but neither one work as expected, either outdated or create xml o html tables or didn't work at all, haven't tried this one though... still creating a helper using PHPExcel shouldn't give you much trouble, you may use this tutorial as a how to base to modify the helper.
I think you need to set the mime-type. This has happened to me in the past and it was when the mime-type of an older excel helper was set to an out-dated value.
The code from the linked (by Ivo) helper has the following:
function _output($title) {
header("Content-type: application/vnd.ms-excel");
header('Content-Disposition: attachment;filename="'.$title.'.xls"');
header('Cache-Control: max-age=0');
$objWriter = new PHPExcel_Writer_Excel5($this->xls);
$objWriter->setTempDir(TMP);
$objWriter->save('php://output');
}
I would make sure you are:
a) using the newest helper (http://bakery.cakephp.org/articles/melgior/2010/01/26/simple-excel-spreadsheet-helper)
b) that the mime-type is actually set.
c) that that specific mime-type is accurate.

The thing is I have found how upload a document and after that downolad it. But I just want to download it. I want to do it using the UI designer but I dont know how to do it.
Thanks :)
I dont know which tool are you using to design your UI, anyway this is concerning functionality, not design. In that point, i need to know wich language do you want (or can) use. For example, in PHP, it's very simple, you can make something like:
(create php file) downloadpdf.php
1st: (if you want to generate pdf "on the fly":
<?php
function download($foo){
content headers (type, force-download, etc)
database select to get data or harcode it.
echo data
}
?>
and call this function with some id to select from database or something (ignore if you want to hardcode it)
Other option to download a file, if it's stored on server is making a link to this file (statically or dyamically). If you wanna take control to file downloads, check this post:
http://www.media-division.com/the-right-way-to-handle-file-downloads-in-php/
I don't mean that it can be done with UI designer tools, and it's not concerned if it's from a form or not.
Cheers!
You should create link and variable which type is javascript expression. On Variable value write
return "/bonita/portal/" + $data.context.mainDoc_ref.url;
On link URL write your variable and to text
Download: {{context.mainDoc_ref.fileName}}
Here you can find excellent example for this case
I have searched a number of plugins for adding automatic/manual headers/comments/function details in any C/C++ file when open in vim editor, even tried using .vimrc file using autocommands. But they are for while opening a new file. Is there any same for already existing files?
Its very tedious for adding information about a code/function in a large code-base.
lh-cpp provides:
customisable templates for file headers
loaded automatically when a new file is created from the file template, before expanding the dedicated .h/.cpp file template
or on demand as they are 3 ways to trigger a template/snippet expansion (automatically on new files, or on demand with :MuTemplate c/internals/c-file-header here (you can also set an alias to something else) or on snippet expansion). As lh-cpp/mu-template snippets/templates are actually similar to functions/variations points, you can ask to expand only file headers (which are customizable on a per-project basis), or anti-reinclusion guards, and so on.
:DOX command that analyses functions signature to fill the function headers as best as possible
advanced snippets for various kind of classes (entity classes, base classes, copiable classes, exception classes, ...) and should eventually fill as much information as possible in the class doxygen from the class semantics -- I just didn't have enough time yet to implement this feature.
There are at least two approaches, one using abbreviations and one using snippets.
For example, you could use Ultisnips to add a pre established header.
I am trying to develop a plugin/component that can change the media file format from one to another. Specifically, I need it to convert the "tiff" file to array/single copy of "jpg" image file.
Kindly guide, how I can implement it or is there any kind of tutorial link from where either I can download it or take some help to develop it. Thanks in advance.
We did this in our CMS (built on CakePHP 1.2; sorry if there are any significant discrepancies I'm not aware of) using a behaviour. That makes the controller logic very easy (in fact we use a baked controller without any modification at all).
Unfortunately TIFF isn't a supported file format in GD (the default image manipulation library in PHP). You'll need to use ImageMagick or an equivalent tool to do the actual conversion itself, but the logic for implementing it in your CakePHP project won't be any different to what I describe here.
The behaviour (in our case) was used to generate images as thumbnails as well as page resolution and to convert the uploaded file format into JPEG.
In its beforeSave() method it checked that data was specified (and that there was no error), and then pulled the tmp_name value from the posted data (and removed the posted data object).
In its afterSave() method, it actually performed the image conversion task itself (putting the generated images in the expected location on disk), then updated any foreign keys on extended models with the uploaded image's ID. We do this in the afterSave() operation so we have a database ID to use to name the files on disk.
In its afterDelete() method we unlink the files on disk.
Using the behaviour in the model is as simple as telling the model (where ContentImage is the name of the behaviour):
var $actsAs = array('ContentImage');
Although we also use the model to define the output directory since we had a few models that implemented the behaviour, and it felt like the right thing to do, e.g. in the model:
function getThumbnailDir() {
return WWW_ROOT.'img'.DS.'upload'.DS.'thumb';
}
and in the behaviour itself the output path becomes:
$Model->getThumbnailDir().DS.$Model->id.'.jpg'
I want to read a single file (the file is a html document) from my computer and store it in a Corpus (I'm using the package tm).
Do you have any solution to do that?
Here is what I tried :
data<-read.csv(fileName)
c2<-Corpus(VectorSource(data))
it mostly works, but I sometime get the error : more columns than column names
I guess I'm not supposed to use read.csv for a webpage, as I didn't find a better solution.
Thanks for your help =)
A webpage definitely does not conform to the specifications that a CSV should. Instead you probably want to use the readHTMLTable function from the XML package.
This is grabbing from an actual webpage but it should be the same idea
file <- "http://xkcd.com/"
dat <- readLines(file)
c2 <- Corpus(VectorSource(dat))
I am using the Drupal 7 Migrate module to create a series of nodes from JPG and EPS files. I can get them to import just fine. But I notice that when I am done importing them if I look at the nodes it creates, none of the attached filefield and thumbnail files contain filename information.
Upon inspecting the file_managed table I see that both the filename and filemime fields are empty for ONLY the files that I attached via the migrate module. This also creates an issue with downloading the files.
Now I think the problem has to do with the fact that I am using "file_link" instead of "file_copy" as the file operation I specify. The problem is I am importing around 2TB (thats Terabytes) of image files. We had to put in a special request with Rackspace just to get access to that much disk space on our server. So I can't go around copying from one directory to the next because of space issues. So "file_link" seems like the obvious choice.
Now you probably want to see how I am doing this exactly, so here is the code snippet:
$jpg_arguments = MigrateFileFieldHandler::arguments(NULL,
'file_link', FILE_EXISTS_RENAME, 'en', array('source_field' => 'jpg_name'),
array('source_field' => 'jpg_filename'), array('source_field' => 'jpg_filename'));
$this->addFieldMapping('field_image', 'jpg_uri')
->arguments($jpg_arguments);
As you can see I am specifying no base path (just like the beer.inc example file does). I have set file_link, the language, and the source fields for the description, title, and alt.
It is able to generate thumbnails from the JPGs. But still missing those columns of data in the db table. I traced through the functions the best I could but I don't see what is causing this. I tried running the uri in the table through the functions that generate the filename and the filemime and they output just fine. It is like something is removing just those segments of data.
Does anyone have any idea what this could be? I am using the Drupal 7 Migrate module version 2.2. It is running on Drupal 7.8.
Thanks,
Patrick
Ok, so I have found the answer to yet another question of mine. This is actually an issue with the migrate module itself. The issue is documented here. I will be repealing this bounty (as soon as I figure out how).
