Title: Syntax errors with conditional statements included Last modified: August 21, 2016 --- # Syntax errors with conditional statements included * Resolved [gecko_guy](https://wordpress.org/support/users/gecko_guy/) * (@gecko_guy) * [13 years ago](https://wordpress.org/support/topic/syntax-errors-with-conditional-statements-included/) * I’m using the plugin in a slightly unusual way, so not sure if it related to that, but it looks like the CONDITIONAL STATEMENTS INCLUDED in the plugin are actually wrong for Internet Explorer: * ``` is_lt_IE(6) is_lt_IE(7) is_lt_IE(8) is_lt_IE(9) ``` * Above are the tags as displayed at the top of the file, but they were not working when I tried to use them, so looked deeper.: * ``` /** * Conditional to test for less than IE9. * * @return bool * * @deprecated Use the future-proof syntax instead of this function: if(is_ie() && get_browser_version() < 9) { } */ function /** * Conditional to test for less than IE9. * * @return bool * * @deprecated Use the future-proof syntax instead of this function: if(is_ie() && get_browser_version() < 9) { } */ function is_lt_IE9() { if(is_ie() && get_browser_version() < 9) { return TRUE; } else { return FALSE; } } { if(is_ie() && get_browser_version() < 9) { return TRUE; } else { return FALSE; } } ``` * The function is defined as **is_lt_IE9()**, but the included conditional statement at the top is **is_lt_IE(9**) * This is the same for all the “is older than” conditions. * [http://wordpress.org/extend/plugins/php-browser-detection/](http://wordpress.org/extend/plugins/php-browser-detection/) Viewing 10 replies - 1 through 10 (of 10 total) * Plugin Author [Mindshare Labs, Inc.](https://wordpress.org/support/users/mindshare/) * (@mindshare) * [13 years ago](https://wordpress.org/support/topic/syntax-errors-with-conditional-statements-included/#post-3703546) * The is_lt_IE style function are being deprecated (no longer supported). Instead use the new syntax: * `if(is_ie() && get_browser_version() < 9) { }` * I will make sure the code comments get changed in the next release. * Thread Starter [gecko_guy](https://wordpress.org/support/users/gecko_guy/) * (@gecko_guy) * [13 years ago](https://wordpress.org/support/topic/syntax-errors-with-conditional-statements-included/#post-3703547) * Thanks, I tried that originally but get a parse error: * Parse error: syntax error, unexpected T_IF in /wp-content/plugins/foobar/foobar. php(2517) : eval()’d code on line 1 * The old way works, but obviously I don’t want to use a deprecated snippet so it is not ideal. * Plugin Author [Mindshare Labs, Inc.](https://wordpress.org/support/users/mindshare/) * (@mindshare) * [13 years ago](https://wordpress.org/support/topic/syntax-errors-with-conditional-statements-included/#post-3703549) * If you are getting a parse error, double check your PHP syntax. Or post the full code here and I’ll can find it for you. * Thread Starter [gecko_guy](https://wordpress.org/support/users/gecko_guy/) * (@gecko_guy) * [13 years ago](https://wordpress.org/support/topic/syntax-errors-with-conditional-statements-included/#post-3703550) * Thanks, I suspect the problem is actually in the Foobar plugin, which does not recognise the modern syntax. * I will contact the developer and ask them to update their conditional logic functions for the plugin. * Thread Starter [gecko_guy](https://wordpress.org/support/users/gecko_guy/) * (@gecko_guy) * [13 years ago](https://wordpress.org/support/topic/syntax-errors-with-conditional-statements-included/#post-3703551) * Am I being dense? * The function in your plugin is defined as: * `is_lt_IE10()` * I do not need to use the full function in my conditional logic field: * ``` function is_lt_IE10() { if(is_ie() && get_browser_version() < 10) { return TRUE; } else { return FALSE; } } ``` * I can use the is_lt_IE10() statement to call the modern function? * What I should _not_ use is is_lt_IE(10) * I’m no php wizard, so perhaps I have misunderstood the whole thing. * I am using is_lt_IE10() * Is this correct? * Sorry for the trouble… * Plugin Author [Mindshare Labs, Inc.](https://wordpress.org/support/users/mindshare/) * (@mindshare) * [13 years ago](https://wordpress.org/support/topic/syntax-errors-with-conditional-statements-included/#post-3703552) * You shouldn’t use the syntax “is_lt_IE10” or “is_lt_IE” – both of these are being phased out. Instead you should use the much more flexible (and future proof): * ``` if(is_ie() && get_browser_version() < 10) { return TRUE; } else { return FALSE; } ``` * The reason is that we don’t want to have to add a ton of different functions for every single borwser version when one function will do. For example, we will not be adding is_ie11() or is_lt_ie11() * Thread Starter [gecko_guy](https://wordpress.org/support/users/gecko_guy/) * (@gecko_guy) * [13 years ago](https://wordpress.org/support/topic/syntax-errors-with-conditional-statements-included/#post-3703554) * Thanks for taking the time to respond to my questions 🙂 * The way I am using the plugin is simply to display a message if the browser is less than IE10, as all future versions of IE will support the CSS3 styles in use on the site. * The Foobar plugin allows me to insert the simple statement is_lt_IE10() * There is no option to use the full function * ``` if(is_ie() && get_browser_version() < 10) { return TRUE; } else { return FALSE; } ``` * as it returns a parse error. I will only be using this particular notification to tell people using old versions of IE (pre IE10) that their version is old, and that they should consider upgrading. * I am unable to edit the php of the Foobar plugin as it will simply be overwritten next time it is updated, so I guess the question becomes, can I use the deprecated syntax for this one instance as I do not need the full functionality of the PHP Browser Detection plugin? * Could I potentially place the code in my functions.php file and do away with the plugin entirely in this case to lower the footprint? * Plugin Author [Mindshare Labs, Inc.](https://wordpress.org/support/users/mindshare/) * (@mindshare) * [13 years ago](https://wordpress.org/support/topic/syntax-errors-with-conditional-statements-included/#post-3703555) * This is going beyond the scope of support for the actual PHP Browser Detection plugin. There are n almost infinite number of ways you could accomplish what you are trying to do with some basic PHP knowledge. Why not just create a custom function that does whatever you need it to in your functions.php file as you suggested? * ``` function myBrowserError() { if(is_ie() && get_browser_version() < 10) { // do soemthing } else { // do soemthing } } } ``` * And call that from Fubar? I am closing this topic as it is no longer directly related to my plugin, but rather about WordPress development in general. * Thread Starter [gecko_guy](https://wordpress.org/support/users/gecko_guy/) * (@gecko_guy) * [13 years ago](https://wordpress.org/support/topic/syntax-errors-with-conditional-statements-included/#post-3703556) * No problem, thank you * Thread Starter [gecko_guy](https://wordpress.org/support/users/gecko_guy/) * (@gecko_guy) * [13 years ago](https://wordpress.org/support/topic/syntax-errors-with-conditional-statements-included/#post-3703559) * I know you have closed the topic. I’m still mystified as to how the plugin works. * I know it works, because it is doing what I want it to do, but I think we may have been talking at cross purposes. * I am not using the plugin to do anything fancy, or to style things for different browsers, or to write my own functions. * All I am doing is placing is_lt_IE10() in a conditional logic field that is already built into another plugin. * I simply cannot understand the deprecation advice. If I use this statement in the field of the other plugin, it does what I want it to. * Will it stop working when there is an upgrade to your plugin? * I am sure I will figure it out, I’m simply confused by the language. Sorry to raise it again, feel a bit embarrassed to do so.
