ProcessWire SVG favicon with custom color in Admin

[Jonathan Lahijani]

ProcessWire does not use a favicon in the admin backend.  I usually insert a PNG-based one of the ProcessWire P logo to differentiate the frontend and backend of a site, however I upgraded my technique to use an SVG-based one, which has the added benefit of being able to quickly set the fill color.  This is a nice trick, especially if you're working in multiple admin backends of different sites and want to be able to quickly identify which tab belongs to which site by the ProcessWire favicon color alone.

Insert this in /site/templates/admin.php:

wire('adminTheme')->addExtraMarkup('head', "<link type=\"image/svg+xml\" rel=\"shortcut icon\" href=\"data:image/svg+xml,%3Csvg width='256' height='256' viewBox='0 0 256 256' xmlns='http://www.w3.org/2000/svg'%3E%3Cpath fill='#EB1D61' fill-rule='nonzero' d='M234.02346,56.2065308 C226.258185,44.611679 213.340949,31.3634673 200.370381,22.7873303 C173.426584,4.33370224 142.216153,-2.21573572 114.611028,0.642976614 C85.8219124,3.7470262 61.1714319,14.5951995 40.9049183,32.6861551 C22.1317268,49.454423 9.73715371,69.9560838 4.27586162,89.5083961 C-1.24942998,109.060708 -0.513435538,127.162331 1.45988289,140.794549 C3.53986718,154.629436 10.4304818,172.037714 10.4304818,172.037714 C11.8384712,175.376434 13.7904564,176.731123 14.8037821,177.296465 C19.8384108,180.048509 28.105015,177.627137 34.4516337,170.50169 C34.7716313,170.06435 34.9422967,169.45634 34.7716313,168.944332 C33.000978,162.128223 32.3609828,156.997474 31.7316543,153.029411 C30.2916651,145.178619 29.65167,132.026409 30.6116627,119.866214 C31.0916591,113.284776 32.3716494,106.244663 34.6116325,98.8632122 C38.9422665,84.281646 48.0728642,69.0600695 62.3447564,56.4092007 C77.715307,42.7876498 97.4271581,34.3715154 116.16835,32.1954806 C122.738967,31.4061347 135.240206,30.6487893 150.290759,34.3608485 C153.501401,35.1608613 167.282631,38.7555854 182.023853,48.7397449 C192.754438,56.0358614 201.394373,65.0386719 207.346328,73.9454809 C213.404949,82.44695 219.986232,96.783179 221.916885,107.279347 C224.647531,119.226204 224.647531,131.88774 222.706212,144.218603 C220.30623,156.570801 215.975596,168.581659 209.24498,179.152495 C204.605015,187.344626 194.983755,198.171465 183.613174,206.299595 C173.362585,213.510377 161.66134,218.715793 149.650764,221.595839 C143.57081,223.035862 137.469522,223.95321 131.218903,224.15588 C125.661612,224.32655 118.291001,224.15588 113.117706,223.2812 C105.427098,222.054513 103.82711,220.091815 102.067123,217.425106 C102.067123,217.425106 100.840466,215.505075 100.499135,210.36366 C100.616467,163.376243 100.595134,175.920443 100.595134,151.525387 C100.595134,144.63461 100.371136,138.383844 100.435135,132.709086 C100.755133,123.396937 101.54446,116.996835 108.20041,110.063391 C113.01104,104.953976 119.741656,101.87126 127.154934,101.87126 C129.405583,101.87126 137.160191,101.977929 143.97614,107.642019 C151.282751,113.74345 152.509409,122.084916 152.797407,124.314285 C154.461394,137.359827 145.842792,147.077316 142.536151,149.541355 C138.440182,152.613404 134.760209,154.106761 132.274895,154.981442 C126.984268,156.752137 121.170979,157.264145 115.944352,156.922806 C115.144358,156.869472 114.41903,157.392147 114.259031,158.19216 L112.499044,167.322972 C110.781724,174.256417 114.632361,176.795124 116.872345,177.691138 C124.029624,179.899173 130.376243,180.816521 137.896186,180.251179 C149.426765,179.440499 160.797346,174.896427 170.450607,165.893616 C178.663878,158.085492 183.346509,148.453338 184.946497,137.679832 C186.546485,125.722308 184.466501,112.847436 179.015875,101.945928 C173.021254,89.9244028 162.674665,79.8869091 149.042768,74.393488 C135.272206,68.9747348 124.317622,68.7827317 110.195062,72.3881226 L110.035063,72.4414568 C100.861799,75.5988406 93.0111915,79.4922361 84.8405865,87.9297042 C79.2406288,93.7537973 74.6539968,100.804577 71.8593512,108.762037 C69.0860388,116.783498 68.3393778,122.767594 68.2113788,132.069076 C68.0407134,138.959853 68.3713775,145.359955 68.3713775,151.354717 L68.3713775,190.832681 C68.3713775,203.462216 67.9447141,205.648918 68.3713775,212.145022 C68.6060424,216.454424 69.2033713,221.329168 71.091357,226.566585 C73.0326757,232.337344 77.1073116,238.257439 79.9019571,240.988149 C83.8165942,245.158882 88.7978899,248.508269 93.693853,250.588302 C104.904435,255.569715 120.125653,256.359061 132.466893,255.879054 C140.637498,255.569715 148.85077,254.439031 156.904042,252.529667 C173.010587,248.700272 188.477137,241.734828 202.077034,232.070673 C216.658258,221.798509 229.330162,207.782285 236.327442,195.878095 C245.298041,181.733869 251.100664,165.861616 254.119308,149.552022 C256.839287,133.210428 256.711288,116.452827 253.063316,100.356569 C250.183338,85.4229975 242.492729,69.0387358 233.61813,55.8118579 L234.02346,56.2065308 Z'%3E%3C/path%3E%3C/svg%3E%0A\">");

Replace the fill color (#EB1D61 -- the PW pink color) with your own brand color if needed.

Note: this is not tested on Safari (doesn't support svg favicons) so make sure to implement a proper fallback if that's important to you.

Thx for sharing ? Just a FYI: TracyDebugger has a similar feature ?

I'll have to do some more investigating as to why, but currently for whatever reason my favicon isn't properly rendering. I'm instead getting a default error image of the web globe, whereas another SVG image worked as expected. If I figure it out I'll post back. That said, I think this idea is an excellent one, a fairly simple addition, and one that I think could be added to core.

 

EDIT:

For whatever reason, I ran it through a PHP urldecode, then re-urlencode'd it; the issue seemed to be with the hash symbol for the fill color not being encoded... (Though if part of the core, it could simply link to a core file, via an auto-generated redirect/include from a site file in admin.php which would be easier [to customize and/or load], and be cacheable).
