php - display tags one by one -

-

hi have tags in database in row called tags. separated commas.

for example, stored in database tag1,tag2,tag3.

i want retrieve them database , display them 1 one separately , before displaying each tag, want link url.

here's doing far,

$keywords = strip_tags($blog_query_results['keywords']); //retrives tags database  echo wordwrap(stripslashes($keywords), 65, "<br>",true); // prints tag1,tag2, , on.

while printing them want link tag1, tag2, , tag3 different urls.

if have string :

$tags = 'tag1,tag2,tag3';

you can use explode() function array of tags :

$arr = explode(',', $tags);

and, then, iterate on array, build link each item -- typically, using foreach() :

foreach ($arr $t) {     echo '<a href="...">' . htmlspecialchars($t, ent_compat, 'utf-8') . '</a><br />'; }


sidenote : database's design bit wrong, if store more 1 information in single field.

if have 3 tags post, should have 3 rows (one per tag), either :

  • in tags table,
  • or in join-table between posts , tags tables.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
