I want to enter a € sign using latex, but the normal codes
\EUR{}
\euro
\text{€}
are not working.
I know it can be done using \usepackage{eurosym} but that does not work either. Can you help me?
Hello,
I get the error “Formular does not parse”, when I write < or > in Latex. How can I say 5 is greater than 4 without > < ?
You can see the error here: https://www.freiereferate.de/mathematik/lineare-ungleichungen
The first error looks like this in the code:
<p><b>Definition:</b> Seien [latex]a,b[/latex] reellen Zahlen. Dann hei?en [latex]ax\leq b[/latex] , [latex]ax < b[/latex] bzw. [latex]ax\geq b[/latex] , [latex]ax> b[/latex] lineare Ungleichungen.</p>
Hi,
there any way to show latex in the titles of the posts?
The plugin works great but it would be much better if you could solve this ??
Thanks a lot.
]]>I understand that the plugin “Beautiful Math” from Jetpack is recommended for use with Sensei. I figured that since this plugin may work as well. I can get equations to display in my posts, but not in my questions.
Does anyone know if this is possible?
Jetpack seems like overkill for this.
Thank you in Advance!
]]>A missing feature is to be able to style inline equations differently than block or stand alone equations. in the following code, I allow for a “isblock’ flag, which adds an additional class tag: “latex_block”.
// [latex size=0 color=000000 background=ffffff isblock=true]\LaTeX[/latex]
// Shortcode -> <img> markup. Creates images as necessary.
function shortcode( $_atts, $latex ) {
$atts = shortcode_atts( array(
‘size’ => 0,
‘color’ => false,
‘background’ => false,
‘isblock’ => false,
), $_atts );
$latex = preg_replace( array( ‘#<br\s*/?>#i’, ‘#</?p>#i’ ), ‘ ‘, $latex );
$latex = str_replace(
array( ‘<‘, ‘>’, ‘"’, ‘“’, ‘”’, ‘'’, ‘᾽’, ‘᾿’, ‘’’, ‘&’, ‘&’, “\n”, “\r”, “\xa0”, ‘–’ ),
array( ‘<‘, ‘>’, ‘”‘, ‘‘, “””, “‘”, “‘”, “‘”, “‘”, ‘&’, ‘&’, ‘ ‘, ‘ ‘, ‘ ‘, ‘-‘ ),
$latex
);
$latex_object = $this->latex( $latex, $atts[‘background’], $atts[‘color’], $atts[‘size’] );
$url = esc_url( $latex_object->url );
$alt = esc_attr( is_wp_error($latex_object->error) ? $latex_object->error->get_error_message() . “: $latex_object->latex” : $latex_object->latex );
// added by tim
$classString = $atts[‘isblock’] ? “latex latex_block” : “latex”;
return “<img src=’$url’ alt=’$alt’ title=’$alt’ class=’$classString’ />”;
}
Then you can add css such as this:
img.latex_block {
display: block;
margin-left: auto;
margin-right: auto;
margin-bottom: 30px;
}
Pleas consider adding this. Thanks!
]]>Hi Guys!
I didn’t touch my site since all was fine on Friday, and came into work today and all the latex equations are broken. They show pictures of little broken images. https://www.tozzo.net
Could you steer me in the right direction please?

]]>I have to following code that does not parse:
$$T_{aussen} \approx?273^\circ K + 25^\circ C \approx 300^\circ K$$
The “same” code does parse:
$$T_{aussen} \approx 273^\circ K + 25^\circ C \approx 300^\circ K$$
The problem seems to be hidden characters. If you look at the url sent to the server you see a difference:
https://s.wordpress.com/latex.php?latex=%20T_%7Baussen%7D%20%5Capprox%80%84273%5E%5Ccirc%20K%20%2B%2025%5E%5Ccirc%20C%20%5Capprox%20300%5E%5Ccirc%20K%20&bg=T&fg=000000&s=0
https://s.wordpress.com/latex.php?latex=%20T_%7Baussen%7D%20%5Capprox%20273%5E%5Ccirc%20K%20%2B%2025%5E%5Ccirc%20C%20%5Capprox%20300%5E%5Ccirc%20K%20&bg=T&fg=000000&s=0
%80%84 are the bad once. Other characters producing the same problem are %E2 and %C2.
I don’t know how to handle this. Some times the characters get added by simply copying the code from one place in the text to an other.
Any ideas?
Thanks!!!

]]>The wp-latex plugin is hardcoded to use https://s.wordpress.com/latex.php as the WordPress.com LaTeX server, even when accessing the site over HTTPS. The URL in line 51 of automattic-latex-wpcom.php should be changed from https://s.wordpress.com/latex.php to //s0.wp.com/latex.php to be protocol agnostic and properly support secure connections.
Hello,
can I change for default on all sites that uses latex the line-height or the font-size? I don’t want to make this on every side manually.
Sometimes the Latex-code isn’t good readable like on this site:
https://www.freiereferate.de/mathematik/pq-formel (see here “Beispiel 2”)
or on this site:

]]>I tried to set a size for my Latex formula, but it did not work as expected:
(#1) Not working: $latex e^{\i \pi}&s=4$
(#2) Working: $latex e^{\i \pi}& amp;s=4$
(without the space)
I changed in wp-latex.php the regular expression so it includes
the non-escape ampersand:
wp-latex,php line 118:
preg_match( '/.+((?:& #038;|& amp;|&)s=(-?[0-4])).*/i', ...<br />
Now, both versions work.
Do I miss an option that makes #1 work out of the box? If not,
would you change the regular expression for the next WP Latex relase,
please?
Kind Regards
Stefan

]]>I have install the latex but don,t know how to insert the math equation in post . please help me.
]]>Hey,
I’ve just started using LaTeX to WordPress. I added a very simple line:
The equation of motion for an electron with charge $latex {-e}$ and mass $latex {m}$ etc etc…
And it converts with newlines before and after every formula. Is there a way to fix it? I posted it here:
https://www.opencodices.com/try/
so you can see what I mean.
Thank you so much!
]]>As far as I can tell the equations just don’t display at all in RSS.
I’m wondering if there’s a way to manage that???? perhaps at least displaying an image? or maybe a box saying something like “math seen on main site” with a link to the single post page?
thoughts?
]]>I installed WP LaTex (1.8) on a test blog running WP 3.5 and set it up to do local LaTex generation. I already had LaTex and dvipng installed because I use LaTex for items in a wiki on the system. Everything worked fine.
I then installed WP LaTex on another WP installation on the same system. This one was running 3.5.2, since upgraded to 3.6. In both cases, I can’t recreate the local LaTex generation. I get “path not found” error for LaTex and dvipng.
These WP installations are running on the same virtual server, so I can’t think of any reason why one installation can find LaTex and dvipng and another can’t.
]]>Refer to this site: https://testlab.peguru.com/test-post-with-latex/

I’m not sure why inputenc doesn’t accept ‘latin1’… In fact, there’s no unicode characters used in the example view. So, the problem is not the .php file, I guess.
Of course, everything works fine when the setting uses ‘WordPress.com’.

Do not know if it is the right place for this but … ??
Trying to use WP Latex in local mode (latex+dvipng), I found that the strings are “-delimited instead of ‘-delimited. It may interact with latex commands beginning by \…

LaTeX converts expressions with $[content]$ into image.
Is there a way to disable LaTeX in certain posts?
