Apesar dofato deeupegarmuito,nãoencontrei a respostapara umaperguntamuito simples:

Eutenho algunsposts com um campopersonalizado (isto é,supplier_name).Eugostaria depoderpesquisare filtrarmeusposts de acordo comeste campopersonalizado.Em outraspalavras,na listagem depostagens de administrador,gostaria deter uma caixa depesquisa (nomeada "nome dofornecedor") ondeposso digitar um valor (ex. Ibm ")e,em seguida,cliqueem umbotão depesquisa que daráMe de voltatodas aspostagens quetêm um campopersonalizado chamado "supplier_name"e,se assimfor,o valor do campopersonalizado será "IBM".

Comopossofazerisso?

Despite the fact I googled a lot, I've not found the answer to a very simple question :

I have some posts with a custom field (i.e. supplier_name). I would like to be able to search and filter my posts according to this custom field. In other words, in the admin posts listing, I would like to have a search box (named "Supplier name") where I can type in a value (ex. "IBM") and then, click on a search button that will give me back all the posts that have a custom field named "supplier_name" and, if so, the value of the custom field will be "IBM".

How can I do this ?

}

I coded a plugin just for that and never got around to publish it :

enter image description here

Usage:

In the dropdown you have a list of all custom fields, so just select the field you want to filter by and click filter. if you want to filter to a specific value of a custom field then select the field's name , enter the value you want and click filter.

}

Por quenão usar afunção auxiliarpara a sua caixa de seleção?ou seja.Substitua `$ CAMPE [0]==$ atual?'selecionado="selecionado":' ', `com` seleccionado ($field [0]==$ corrente,verdadeiro,falso),`... :)

Why not use the helper function for your selection box? ie. replace `$field[0] == $current? ' selected="selected"':'', ` with `selected( $field[0] == $current, true, false ),` ... :)
