Android Question View php in webwiew

Adamdam · Sep 9, 2019

Dear All,
Greetings,

I retrieve message from remote database, it seem like as following :

Product information

it seem like part of php script.
so, I add header and footer to make it as part of HTML like the following :

<html>
<body>
<?php
$string = "Product information";
$string = html_entity_decode($string);
echo $string;
?>
</body>
</html>

but the webview didn't view it

The code (of what mentioned above) as following:

Dim str As String
str = "<html><body><?php $string =" & Chr(34) & "Product information" & Chr(34) & ";$string = html_entity_decode($string); echo $string; ?></body></html>"
Webview1.LoadHtml(ss)
'ProdWeb.LoadUrl("www.vertex-technology.com")
Webview1.Invalidate

After many testing, I found that : Webview didn't view any php script inside,

Any suggestion to view the above message.

Thanks in advance.

best regards

On web server running php, php return a html code.
The webView do not handle php code because webview don't have a php engine

B4X:

Dim str As String
str = "&lt;p&gt;&lt;span style=&quot;font-size: 13px;&quot;&gt;Product &lt;b&gt;information&lt;/b&gt;&lt;/span&gt;&lt;/p&gt;"
Webview1.LoadHtml(str)

no, it is kind of encoded html code

You should decode the html before sending the result (echo)

PHP:

$string = "&lt;p&gt;Blah blah description is here blah blah&lt;p&gt;"; # this is the code from the database.
$string = html_entity_decode($string);
#$string = strip_tags($string); # Remove htmlcode (if you want)
echo $string; # This is what you should return to the calling B4A

because you will have html, the output of
< is the < char
> is the > char
" is "

First many thanks for all,

Many thanks for Mr. Brandsum and Mr. DonManfred and Mr. MarkusR
I test all solutions:
for solution from Mr. Brandsum
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
Dim str As String
str = "Product information"
Webview1.LoadHtml(str)
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
The output in webview seem like " ... " as shown in attached image

for the solution from Mr. DonManfred
I write it as following :
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
Dim str As String
str = "<html><body><?php $string = " & Chr(34) & "Product information" & Chr(34) & "; $string = html_entity_decode($string); $string = strip_tags($string); echo $string; ?></body></html>"
Webview1.LoadHtml(str)
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''

The webview didn't display any things,
- If I write right code as you suggest ?
- may be webview old version ??, and need to use other library ??

Thanks in advance
Best regards

in the first the start and end is missing <html><body>
and in the second php script is executed via a php.exe interpreter that outputs something.
php is a installed part of a web server, i guess you saw a webside with .php ending,
this file contains the php script inside this <?php a script is here ?>
inside of php you can output text with echo into the http request result.

B4X:

Public Sub decode(Raw As String) As String
    Return Raw.Replace("&quot;",QUOTE).Replace("&apos;","'").Replace("&lt;","<").Replace("&gt;",">").Replace("&amp;","&")
End Sub

Dim str As String
str = decode("&lt;p&gt;&lt;span style=&quot;font-size: 13px;&quot;&gt;Product &lt;b&gt;information&lt;/b&gt;&lt;/span&gt;&lt;/p&gt;")
Webview1.LoadHtml(str)
