Question

PHP Need to remove invisible control Characters...

Asked by: CrisThompsonUK

AhhhrrrgGGG!

Enough fighting with it, over to you, experts...

I'm reading a string of HTML from my content database, and popping it up in javascript 'tool tip' type type of way...

But the javascript fails when there are invisible return(or line feed?) characters in the text string...


Let me show you...

This works:
<a href="event_detail.php?event=4" onMouseover="ddrivetip('<div class=\'event_list_title\'>new test<br>(Training)</div><div class=\'event_list_detail\'><p>Event Tour</p><p>A series of one-day seminars...</div>','', 300)" onMouseout="hideddrivetip()" onClick="hideddrivetip()" ><img src="images/calendar_box_foot.gif" border="0"  align="right" width="75" ></a>

but this doesn't work...
<a href="event_detail.php?event=4" onMouseover="ddrivetip('<div class=\'event_list_title\'>new test<br>(Training)</div><div class=\'event_list_detail\'><p>Event Tour</p>
<p>A series of one-day seminars...</div>','', 300)" onMouseout="hideddrivetip()" onClick="hideddrivetip()" ><img src="images/calendar_box_foot.gif" border="0"  align="right" width="75" ></a>

The only difference is that after the <p>Event Tour</p> there seems to be an invisible new line or return character that must be interfering with the javascript.

How can I remove this invisible character using PHP?

Hello CrisThompsonUK,

you should use something like that to replace returnCarriage by the html equivalent


$newString = str_replace($oldString,"\r\n","
");
$newString = str_replace($newString,"\n","
");

Regards,

alain34

Alternatively, if you want to strip out the newline characters on the Javascript side  before you call whatever javascript function is giving you trouble, you can do this:

mytext.replace(/\r|\n|\r\n/g, "")
