[Qgis-user] Expression to read field value from composer layout?

[Stefan Giese (WhereGroup)]

here is a function which does the job. It's a bit more generic, you have 
to pass the layoutname and the itemID to get the text:

/from qgis.core import *//
//from qgis.gui import *//
//
//@qgsfunction(args='auto', group='Custom')//
//def get_layout_textitem(layoutTitle, itemId, feature, parent)://
//    """//
//    Gets the text from a labelitem in the layout with the name 
layoutTitle.//
//    <h2>Example usage:</h2>//
//    <ul>//
//      <li>get_layout_textitem('Layout 1', 'text1') -> 'lorem ipsum</li>//
//    </ul>//
//    """//
//
//    project = QgsProject.instance()//
//    projectLayoutManager = project.layoutManager()//
//    layout = projectLayoutManager.layoutByName(layoutTitle)//
//
//    fileNameLabel = layout.itemById(itemId)//
//    fileNameText = fileNameLabel.text() //
//    return fileNameText/

//
