Hi

I was wondering, how do you read a text file on a server in javascript?


Thanks.

I recall Ajax lets you do that. Otherwise, include it with PHP first.

HTML5 browsers should have 'File API' support. I think you want FileReader.readAsDataURL(). I've never used it myself but it might work.

Hi

I am trying to read a file in php: Pic1 and Personsnamejs are javascript variables.



<?php


echo "<script>var Pic1=$('#Graphic_select').val();</script>";

$pic="<script>document.writeln(Pic1);</script>";



$Pricefile = str_replace(".jpg",".log",$pic);



echo "<script>var Person = personsnamejs;</script>";

$Personsnamejs = "<script>document.writeln(Person);</script>";




$path = "https://ecovib2d.com.au/workfromhome/yourart/".$Personsnamejs."E/Prices/".$Pricefile;


$fo=fopen($path,"r");



$Priceofart =fread($fo,filesize($path));
fclose($fo);


?>


With the above code I get the following warning:


[03-Jan-2021 09:55:11 UTC] PHP Warning: fopen(https://ecovib2d.com.au/workfromhome/yourart/&lt;script&gt;document.writeln(Person);&lt;/script&gt;E/Prices/&lt;script&gt;document.writeln(Pic1);&lt;/script&gt;): failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found

Any help will be appreciated.

Thanks.

I am trying to read a file in php: Pic1 and Personsnamejs are javascript variables.

That can't work, since PHP runs on the server before the web page is sent to the browser, only after that is the javascript run in the browser. However, Ajax does let javascript make calls to the server and run e.g. PHP.

From where do you get the values for Pic1 and Personsnamejs in the first place?

Hi


Thanks for that.


I am trying to read a txt file on the server using jquery (below):


Pricefile = Pic1.replace(".jpg",".log");


var Pricepath = 'https://ecovib2d.com.au/workfromhome/yourart/' + personsnamejs + 'E/Prices/' + Pricefile;


// read *.log files

jQuery.get(Pricepath, function(data) {




$().html('Price of your Art (AUD): $' + data + ' including GST ');

document.getElementById('Cost').value = data;

});

I am having trouble displaying the html content once and on one line.

Can you please help?

Thanks.

Adrian.

Hi guys




Problem solved:


$.get(Pricepath, function(data) {




var Priceofart = data;



$('#Price2').html(function (){


return 'Price of your Art (AUD): $' + data + ' including GST ';


});

return Priceofart;

},"text");
